One-pot synthesis of five substituted tetrahydropyridines using nano-Al2O3/BF3/Fe3O4 as a highly efficient nano-catalyst

Nano-Al2O3/BF3/Fe3O4 was synthesized as an efficient and reusable catalyst. The synthesized magnetic catalyst has been characterized by various methods such as FT-IR, FESEM, TGA, TEM, VSM, XRF, XRD and BET. This catalyst does not need special precautions for preparation, handling or storage, and it can be stored at an ambient temperature for months without losing its catalytic activity. Five-substituted tetrahydropyridines and their derivatives have an interesting class of pharmaceutical activities. Thus, the nano-Al2O3/BF3/Fe3O4 catalyst was used to prepare five-substituted tetrahydropyridines by one-pot multicomponent reactions of aromatic aldehydes, anilines and beta-keto-esters under solvent free conditions. The structure of products were studied by Fourier transform spectroscopy and nuclear magnetic resonance. The present protocol has notable advantages of easy purification, clean and convenient procedure and high yields for isolated products. In addition, this catalyst could be recycled several times without reduction in its admirable activity. [GRAPHICS] .

Catalytic Asymmetric Reactions with N-Metallated Azomethine Ylides

Optically active nitrogen-containing compounds have attracted substantial attention due to their ubiquity in the cores of natural products and bioactive molecules. Among the various synthetic approaches to nitrogenous frameworks, catalytic asymmetric 1,3-dipolar cycloadditions are one of the most attractive methods because of their powerful ability to rapidly construct various chiral N-heterocydes. In particular, N-metallated azomethine ylides, common and readily available 1,3-dipoles, have been extensively applied in dipolar cydoaddition reactions. Despite the fact that asymmetric transformations of azomethine ylides have been investigated for decades, most of the efforts have been directed toward the preparation of pyrrolidines using glycinate-derived alpha-unsubstituted aldimine esters as the precursors of the azomethine ylides. While alpha-substituted azomethine ylides derived from amino esters other than glycinate have seldom been harnessed, the construction of non-five-membered chiral N-heterocycles via 1,3-dipolar cycloadditions remains underexplored. In addition, the asymmetric alpha-functionalization of aldimine esters to prepare acyclic nitrogenous compounds such as alpha-amino acids, in which an in situ-generated N-metallated azomethine ylide serves as the nucleophile, has not been sufficiently described. In this Account, we mainly discuss the achievements we have made in the past decade toward broadening the applications of N-metallated azomethine ylides for the preparation of nitrogen-containing compounds. We began our investigation with the design and synthesis of a new type of chiral ligand, TF-BiphamPhos, which not only coordinates with Lewis acids to activate dipolar species but also serves as an H-bond donor to increase the reactivity of dipolarophiles with significantly enhanced stereochemical control. Using the Cu(I) or Ag(I)/TF-BiphamPhos complex as the catalyst, we achieved highly stereoselective (3+2) cycloadditions of glycinate and non-glycinate-derived azomethine ylides with diverse dipolarophiles, producing a variety of enantioenriched pyrrolidines with multiple stereocenters in a single step. To further expand the synthetic utility of N-metallated azomethine ylides, we successfully developed higher order cycloadditions with fulvenes, tropone, 2-aryl cydoheptatrienes, and pyrazolidinium ylides serving as the reaction partner, and this reaction provides straightforward access to enantioenriched fused piperidines, bridged azabicyclic frameworks, and triazines via (3+6)- and (3+3)-type cycloadditions. Using N-metallated azomethine ylides as the nucleophile, we realized Cu(I)-catalyzed asymmetric 1,4-Michael additions with alpha,beta-unsaturated bisphosphates/Morita-Baylis-Hillman products, furnishing an array of structurally diverse unnatural alpha-amino acids. Based on the strategy of synergistic activation, we achieved highly efficient dual Cu/Pd and Cu/Ir catalysis for the alpha-functionalization of aldimine esters via the asymmetric allylic/allenylic allcylation of N-metallated azomethine ylides. Notably, Cu/Ir catalysis allowed the stereodivergent synthesis of alpha,alpha-disubstituted alpha-amino acids via a branched allylic alkylation reaction, in which the two distinct chiral metal catalysts independently have full stereochemical control over the corresponding nucleophile and electrophile. Furthermore, an expedient and stereodivergent preparation of biologically important tetrahydro-gamma-carbolines was realized through a Cu/Ir-catalyzed cascade allylation/iso-Pictet-Spengler cyclization. In addition, when the steric congestion in the allylation intermediates was increased, the combined Cu/Ir catalysts provided an asymmetric cascade allylation/2-aza-Cope rearrangement, producing various optically active homoallylic amines with impressive results.

Imipenem-Relebactam and Meropenem-Vaborbactam: Two Novel Carbapenem-beta-Lactamase Inhibitor Combinations

Relebactam (formerly known as MK-7655) is a non-beta-lactam, bicyclic diazabicyclooctane, beta-lactamase inhibitor that is structurally related to avibactam, differing by the addition of a piperidine ring to the 2-position carbonyl group. Vaborbactam (formerly known as RPX7009) is a non-beta-lactam, cyclic, boronic acid-based, beta-lactamase inhibitor. The structure of vaborbactam is unlike any other currently marketed beta-lactamase inhibitor. Both inhibitors display activity against Ambler class A [including extended-spectrum beta-lactamases (ESBLs), Klebsiella pneumoniae carbapenemases (KPCs)] and class C beta-lactamases (AmpC). Little is known about the potential for relebactam or vaborbactam to select for resistance; however, inactivation of the porin protein OmpK36 in K. pneumoniae has been reported to confer resistance to both imipenem-relebactam and meropenem-vaborbactam. The addition of relebactam significantly improves the activity of imipenem against most species of Enterobacteriaceae [by lowering the minimum inhibitory concentration (MIC) by 2- to 128-fold] depending on the presence or absence of beta-lactamase enzymes. Against Pseudomonas aeruginosa, the addition of relebactam also improves the activity of imipenem (MIC reduced eightfold). Based on the data available, the addition of relebactam does not improve the activity of imipenem against Acinetobacter baumannii, Stenotrophomonas maltophilia and most anaerobes. Similar to imipenem-relebactam, the addition of vaborbactam significantly (2- to > 1024-fold MIC reduction) improves the activity of meropenem against most species of Enterobacteriaceae depending on the presence or absence of beta-lactamase enzymes. Limited data suggest that the addition of vaborbactam does not improve the activity of meropenem against A. baumannii, P. aeruginosa, or S. maltophilia. The pharmacokinetics of both relebactam and vaborbactam are described by a two-compartment, linear model and do not appear to be altered by the co-administration of imipenem and meropenem, respectively. Relebactam’s approximate volume of distribution (V (d)) and elimination half-life (t (A 1/2)) of similar to 18 L and 1.2-2.1 h, respectively, are similar to imipenem. Likewise, vaborbactam’s V (d) and t(A 1/2) of similar to 18 L and 1.3-2.0 h, respectively, are comparable to meropenem. Like imipenem and meropenem, relebactam and vaborbactam are both primarily renally excreted, and clearance correlates with creatinine clearance. In vitro and in vivo pharmacodynamic studies have reported bactericidal activity for imipenem-relebactam and meropenem-vaborbactam against various Gram-negative beta-lactamase-producing bacilli that are not inhibited by their respective carbapenems alone. These data also suggest that pharmacokinetic-pharmacodynamic parameters correlating with efficacy include time above the MIC for the carbapenems and overall exposure for their companion beta-lactamase inhibitors. Phase II clinical trials to date have reported that imipenem-relebactam is as effective as imipenem alone for treatment of complicated intra-abdominal infections and complicated urinary tract infections, including acute pyelonephritis. Imipenem-relebactam is currently in two phase III clinical trials for the treatment of imipenem-resistant bacterial infections, as well as hospital-associated bacterial pneumonia (HABP) and ventilator-associated bacterial pneumonia (VABP). A phase III clinical trial has reported superiority of meropenem-vaborbactam over piperacillin-tazobactam for the treatment of complicated urinary tract infections, including acute pyelonephritis. Meropenem-vaborbactam has recently demonstrated higher clinical cure rates versus best available therapy for the treatment of carbapenem-resistant Enterobacteriaceae (CRE), as well as for HABP and VABP. The safety and tolerability of imipenem-relebactam and meropenem-vaborbactam has been reported in various phase I pharmacokinetic studies and phase II and III clinical trials. Both combinations appear to be well tolerated in healthy subjects and hospitalized patients, with few serious drug-related treatment-emergent adverse events reported to date. In conclusion, relebactam and vaborbactam serve to broaden the spectrum of imipenem and meropenem, respectively, against beta-lactamase-producing Gram-negative bacilli. The exact roles for imipenem-relebactam and meropenem-vaborbactam will be defined by efficacy and safety data from further clinical trials. Potential roles in therapy for these agents include the treatment of suspected or documented infections caused by resistant Gram-negative bacilli-producing ESBL, KPC, and/or AmpC beta-lactamases. The usage of these agents in patients with CRE infections will likely become the standard of care. Finally, increased activity of imipenem-relebactam against P. aeruginosa may be of clinical benefit to patients with suspected or documented P. aeruginosa infections.

Use of LC-MS analysis to elucidate by-products of niacinamide transformation following in vitro skin permeation studies

Objective To explore and elucidate the formation of niacinamide (NIA) by-products during in vitro skin permeation studies using liquid chromatography coupled to mass spectrometry (LC-MS) analysis. MethodsResultsPorcine skin permeation studies of various NIA formulations were conducted using Franz diffusion cells for a period of 24 hours. NIA by-products were identified by LC, extracted and further qualitatively analysed by LC-MS. Analysis and characterisation of NIA by-products using LC-MS resulted in the identification of different molecular entities with similar structures to NIA. The most prevalent molecular specie in this study was 1,4,5,6-tetrahydropyridine-3-carboxamide with the highest ion abundance. Other structural NIA analogues were also identified and reported, namely piperidine-3-carboxamide and 1,4-dihydropyridine-3-carboxamide. None of these NIA derivatives were detected in stability studies of NIA in the medium used as the receptor phase, phosphate buffered saline (PBS), that had not been in contact with skin. ConclusionResumeThe comparatively low recovery of NIA following in vitro mass-balance and permeation studies for pseudo-finite and finite dosing of the active compared with infinite dosing is attributed to chemical derivatisation of the molecule during skin penetration. These findings reported here will allow the development of more sensitive methods to ensure full mass balance recovery of NIA following topical application of NIA preparations. ObjectifMethodesEtudier et elucider la formation de sous-produits du niacinamide (NIA) pendant les etudes de permeation cutanee in vitro en utilisant la chromatographie en phase liquide couplee a l’analyse par spectrometrie de masse (liquid chromatography-mass spectrometry ou LC-MS).

Les sous-produits du NIA ont ete identifies par LC, extraits et analyses de facon plus approfondie sur le plan qualitatif par LC-MS. ResultatsConclusionL’analyse et la caracterisation des sous-produits du NIA a l’aide de la LC-MS ont permis d’identifier differentes entites moleculaires ayant des structures similaires au NIA. L’espece moleculaire la plus repandue dans cette etude etait le 1,4,5,6-tetrahydropyridine-3-carboxamide avec la plus grande abondance d’ions. D’autres analogues structuraux du NIA ont egalement ete identifies et signales, a savoir la piperidine-3-carboxamide et le 1,4-dihydropyridine-3-carboxamide. Sans contact avec la peau, aucun de ces derives du NIA n’a ete detecte dans les etudes de stabilite du NIA dans le milieu utilise comme phase receptrice, (tampon phosphate salin – PBS). La recuperation relativement faible du NIA a la suite d’etudes in vitro de bilan massique et de permeation pour le dosage pseudo-fini et fini de l’actif par rapport au dosage infini est attribuee a la derivatisation chimique de la molecule lors de la penetration cutanee. Les resultats presentes ici permettront de mettre au point des methodes plus sensibles pour assurer la recuperation complete du bilan massique du NIA a la suite de l’application topique des preparations de NIA.

Click-Addressable Cassette for Photoaffinity Labeling

A small molecule 1 was designed to contain an alkyne, a trifluoromethyl phenyldiazirine, and a free piperidine-NH for facile conjugation to protein binding ligands. This cassette 1 was synthesized via a relatively direct route involving only routine steps. In this proof-of-concept study, putative ligands for carbonic anhydrase IX and for TrkC were conjugated to 1. Photoaffinity labeling was performed using purified extracellular regions of both these protein-receptors, and using cells that express these receptors (isolation via a pull-down procedure), labeling of the protein was observed in all four experiments.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 5570-77-4. COA of Formula: C6H12ClN.

Determination and Prediction of Dissociation Constants and Related Thermodynamic Properties for 2-(Butylamino)ethanol, m-Xylylenediamine, 3-Picolylamine, Isopentylamine, and 4-(Aminoethyl)-piperidine

The present study reports on the experimental measurement of the dissociation constants and the determination of related thermodynamic properties for five amines of importance in the area of CO2 capture. Measurements were performed for 2-(butylamino)ethanol, m-xylylenediamine, 3-picolylamine, isopentylamine, and 4-(aminoethyl)-piperidine. The experiments were done at an average pressure of 95.0 kPa and in a temperature range varying from 288.15 to 323.15 K. pK(a) measurements were performed using the potentiometric titration method. Based on the experimental data obtained, thermodynamic properties such as the standard state enthalpy, entropy, and free energies were regressed using the van’t Hoff equation. Gaussian was used to determine in the case of diamines which amino group in the molecule would react first in the titration when the structure was unsymmetrical. In addition, the Perrin-Dempsey-Serjeant prediction model and its updated version were used to predict the first pK(a) values.

Intermolecular interactions in hydrates of 4-methylpiperidine and 4-chloropiperidine – a structural and computational study

The structures and interactions in four new hydrates of substituted piperidines have been studied using X-ray crystallography and quantum chemistry. The piperidine ring substitution leads to a significant reduction in the number of hydrates compared with the parent amine, with 4-methylpiperidine yielding a hemihydrate and a trihydrate; 4-chloropiperidine a monohydrate and a trihydrate, (where the architecture is similar to 4-methylpiperidine trihydrate). Despite many attempts, it did not prove possible to crystallize hydrates with higher molar amine : water ratios. Therefore, trihydrates are probably the most hydrated crystals to be obtained at ambient pressure for both amines. Both trihydrates create identical water layers of the L4(6)5(7)6(8) type and the main structural difference is the arrangement of hydrogen bonds between water layers and amines. Despite this, both trihydrates have the same melting temperature (263 K) and as supported by lattice energy calculations. Chlorine.chlorine contacts have no significant impact on the stabilization of the 4-chloropiperidine monohydrate or the 4-chloropiperidine trihydrate. Periodic DFT-D3 calculations show that the energies of the water layers are identical in both cases, and the summed hydrogen bond energies (although arranged differently) are similar. Moreover, in the case of trihydrates, which have a 2-D topology of water…water interactions, it is possible to perform DFT calculations for separate layers and to determine the contribution of those interaction energies to the cohesive energy of the whole crystals.

Structural diversity in copper(I) iodide complexes with 6-thioxopiperidin-2-one, piperidine-2,6-dithione and isoindoline-1,3-dithione ligands

Copper(I) iodide complexes are well known for displaying a diverse array of structural features even when only small changes in ligand design are made. This structural diversity is well displayed by five copper(I) iodide compounds reported here with closely related piperidine-2,6-dithione (SNS), isoindoline-1,3-dithione (SNS6), and 6-thioxopiperidin-2-one (SNO) ligands: di-mu-iodido-bis[(acetonitrile-kappa N)(6-sulfanylidenepiperidin-2-one-kappa S)copper(I)], [Cu2I2(CH3CN)(2)(C5H7NOS)(2)] (I), bis(acetonitrile-kappa N)tetra-mu(3)-iodido-bis(6-sulfanylidenepiperidin-2-one-kappa S)-tetrahedro-tetracopper(I), [Cu4I4(CH3CN)(4)-(C5H7NOS)(4)] (II), catena-poly[[(mu-6-sulfanylidenepiperidin-2-one-kappa O-2: S)copper(I)]-mu(3)-iodido], [CuI(C5H7NOS)](n) (III), poly[[(piperidine-2,6-dithione-kappa S)copper(I)]-mu(3)-iodido], [CuI(C5H7NS2)](n) (IV), and poly[[(mu-isoindoline-1,3-dithione-kappa S-2:S)copper(I)]-mu(3)-iodido], [CuI(C8H5NS2)](n) (V). Compounds I and II crystallize as discrete dimeric and tetrameric complexes, whereas III, IV, and V crystallize as polymeric two-dimensional sheets. To the best of our knowledge, compound III is the first instance of an extended hexagonal [Cu3I3] structure that is not supported by bridging ligands. Structures I, II, and IV display weak to moderately strong Cu center dot center dot center dot Cu cuprophilic interactions [Cu center dot center dot center dot Cu internuclear distances range between 2.5803 (10) and 2.8485 (14) angstrom]. All structures except III display weak hydrogen-bonding interactions between the N-H of the ligand and the mu(2) and mu(3)-I- atoms. Structure III contains classical N-H center dot center dot center dot O interactions between the SNO ligands that connect the molecules in a three-dimensional framework. Complex V features pi-pi stacking interactions between the aryl rings of the SNS6 ligands within the same polymeric sheet. In structure IV, there were three partially occupied solvent molecules of dichloromethane and one partially occupied molecule of acetonitrile present in the asymmetric unit. The SQUEEZE routine [Spek (2015). Acta Cryst. C71, 9-18] was used to correct the diffraction data for diffuse scattering effects and to identify the solvent molecules.
