Asymmetric Synthesis of (-)-Indolizidine167B and (+)-Coniine

The enantioselective syntheses of (-)-indolizidine 167B and (+)-coniine were described based on the asymmetric hydrogenation of racemic d-hydroxy esters via kinetic resolution. With optically active chiral d-hydroxy ester (S)-4 and chiral 1,5-diol (R)-5 obtained by asymmetric hydrogenation of racemic ethyl 5-hydroxyoctanoate (rac-4) with chiral spiro iridium catalyst Ir-(R)-SpiroPAP as chiral starting materials, the efficient enantioselective syntheses of (-)-indolizidine 167B and (+)-coniine were achieved by using intramolecular reductive amination and N-substitution/cyclization, respectively, as a key step to construct the chiral aza-bicyclic[4.3.0]nonane skeleton and chiral piperidine ring. This provides new efficient methods for enantioselective syntheses of indolizidine and piperidine alkaloids.y

Self-organization of silicates on different length scales exemplified by amorphous mesoporous silica and mesoporous zeolite beta using multiammonium surfactants

In this study the structure directing effect of a gemini-type piperidine-based multi-ammonium surfactant during hydrothermal zeolite synthesis was investigated for two cases: with and without a source of aluminum. The absence of an aluminum source led to the formation of an amorphous mesoporous MCM-48 type silica material, while the presence of aluminum guaranteed the formation of zeolite beta with a hierarchical pore system. The two opposing cases were studied in a time and temperature-dependent manner. The mobility and through space interaction of these large surfactant molecules were studied by liquid state nuclear magnetic resonance (NMR) at a temperature relevant to hydrothermal synthesis (363 K) in pure water and upon addition of an aluminum and silicon source. In the gel state, at different stages of aging and hydrothermal synthesis, low angle X-ray diffraction (XRD) and solid state magic angle spinning nuclear magnetic resonance (H-1 MAS NMR) spectrometry determined the developing order within the system. At each of these different synthesis steps the respective intermediate materials were calcined. Transmission electron microscopy then allowed closer inspection of the locally developing mesoscopic order, while N-2 physisorption was used to follow the evolution of porosity.

Chemical and structural investigation of the paroxetine-human serotonin transporter complex

Antidepressants target the serotonin transporter (SERT) by inhibiting serotonin reuptake. Structural and biochemical studies aiming to understand binding of small-molecules to conformationally dynamic transporters like SERT often require thermostabilizing mutations and antibodies to stabilize a specific conformation, leading to questions about relationships of these structures to the bonafide conformation and inhibitor binding poses of wild-type transporter. To address these concerns, we determined the structures of Delta N72/Delta C13 and ts2-inactive SERT bound to paroxetine analogues using single-particle cryo-EM and x-ray crystallography, respectively. We synthesized enantiopure analogues of paroxetine containing either bromine or iodine instead of fluorine. We exploited the anomalous scattering of bromine and iodine to define the pose of these inhibitors and investigated inhibitor binding to Asn177 mutants of ts2-active SERT. These studies provide mutually consistent insights into how paroxetine and its analogues bind to the central substrate-binding site of SERT, stabilize the outward-open conformation, and inhibit serotonin transport.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 3056-33-5, in my other articles.

Morpholinium and Piperidinium Based Deep Eutectic Solvents for Synthesis of Pyrazole-5-Carbonitriles, Indoles and Tetrazoles: Bulk Properties via Molecular Dynamics Simulations

Deep eutectic solvents (DES) have gained much popularity in the area of green synthetic chemistry, since they act as excellent alternative to traditional organic solvents for carrying out diverse organic reactions and transformations. Furthermore, they are thermally stable over a wide temperature range, they are non-volatile, inert and can be easily recovered and reused after carrying out reactions. In the present study, we have synthesized morpholine and piperidine based ionic liquids, and combined them with different hydrogen bond donors (urea, diethylene glycol (DEG), carboxylic acid, thiourea, ethanol and methanol) to produce different DES melts. These DES melts were then explored for their potential as catalyst/reaction media for carrying out different organic transformations for synthesis of molecules such as pyrazole-5-carbonitriles 5 a-d, Fisher Indoles 8 a-d and 1H-tetrazoles 10 a-b. In DES, the hydrogen bonded interactions between ionic liquids and hydrogen bond donors are known to be crucial for mediating their catalytic and synthetic efficiency, hence molecular dynamics simulations of these DES melts were carried out to investigate and study these effects.

Automatic procedures for the synthesis of difficult peptides using oxyma as activating reagent: A comparative study on the use of bases and on different deprotection and agitation conditions

Solid-Phase Peptide Synthesis (SPPS) is a rapid and efficient methodology for the chemical synthesis of peptides and small proteins. However, the assembly of peptide sequences classified as difficult poses severe synthetic problems in SPPS for the occurrence of extensive aggregation of growing peptide chains which often leads to synthesis failure. In this framework, we have investigated the impact of different synthetic procedures on the yield and final purity of three well-known difficult peptides prepared using oxyma as additive for the coupling steps. In particular, we have comparatively investigated the use of piperidine and morpholine/DBU as deprotection reagents, the addition of DIPEA, collidine and N-methylmorpholine as bases to the coupling reagent. Moreover, the effect of different agitation modalities during the acylation reactions has been investigated. Data obtained represent a step forward in optimizing strategies for the synthesis of difficult peptides.

Structural modification of the tripeptide KPV by reductive glycoalkylation of the lysine residue

Peptides that exhibit enzymatic or hormonal activities are regulatory factors and desirable therapeutic drugs because of their high target specificity and minimal side effects. Unfortunately, these drugs are susceptible to enzymatic degradation, leading to their rapid elimination and thereby demanding frequent dosage. Structurally modified forms of some peptide drugs have shown enhanced pharmacokinetics, improving their oral bioavailability. Here, we discuss a novel glycomimetic approach to modify lysine residues in peptides. In a model system, the epsilon-amine of Ts-Lys-OMe was reductively alkylated with a glucose derivative to afford a dihydroxylated piperidine in place of the amine. A similar modification was applied to H-KPV-NH2, a tripeptide derived from the alpha-melanocyte stimulating hormone (alpha-MSH) reported to have antimicrobial and anti-inflammatory properties. Antimicrobial assays, under a variety of conditions, showed no activity for Ac-KPV-NH2 or the alpha-or epsilon-glycoalkylated analogs. Glycoalkylated peptides did, however, show stability toward proteolytic enzymes.

Synthesis, radiolabelling, and evaluation of [C-11]PB212 as a radioligand for imaging sigma-1 receptors using PET

The Sigma-1 receptor (Sig-1R) has been described as a pluripotent modulator of distinct physiological functions and its involvement in various central and peripheral pathological disorders has been demonstrated. However, further investigations are required to understand the complex role of the Sig-1R as a molecular chaperon. A specific PET radioligand would provide a powerful tool in Sig-1R related studies. As part of our efforts to develop a Sig-1R PET radioligand that shows antagonistic properties, we investigated the suitability of 1-(4-(6-methoxynaphthalen-1-yl) butyl)-4-methylpiperidine (designated PB212) for imaging Sig-1R. PB212 is a Sig-1R antagonist and exhibits subnanomolar affinity (K-i = 0.030 nM) towards Sig-1R as well as good to excellent selectivity over Sig-2R. The radiolabelling of [C-11]PB212 was accomplished by O-methylation of the phenolic precursor using [C-11]MeI. In vitro autoradiography with [C-11]PB212 on WT and Sig-1R KO mouse brain tissues revealed high non-specific binding, however using rat spleen tissues from CD1 mice and Wistar rats, high specific binding was observed. The spleen is known to have a high expression of Sig-1R. In vivo PET experiments in Wistar rats also showed high accumulation of [C-11]PB212 in the spleen. Injection of Sig-1R binding compounds, haloperidol (1 mg/kg) or fluspidine (1 mg/kg) shortly before [C-11]PB212 administration induced a drastic reduction of radiotracer accumulation, confirming the specificity of [C-11]PB212 towards Sig-1R in the spleen. The results obtained herein indicate that although [C-11]PB212 is not suitable for imaging Sig-1R in the brain, it is a promising candidate for the detection and quantification of Sig-1Rs in the periphery.

Unraveling Direct Formation of Hierarchical Zeolite Beta by Dynamic Light Scattering, Small Angle X-ray Scattering, and Liquid and Solid State NMR: Insights at the Supramolecular Level

A case study on the understanding of the formation of hierarchical Beta zeolites using gemini-type piperidine based multiammonium surfactant (N-6-diphe) is reported. Complementary techniques were used to investigate N-6-diphe’s structure-directing effect at the molecular level. Combining characterization of the resulting zeolite materials with the toolboxes herein developed for studying clear solutions and dense gels discloses self-assembly processes that govern the growth (and growth inhibition) of nano-Beta zeolite crystals. In clear solution, small-angle X-ray scattering and liquid-state NMR provide insights about the formation of nanoparticles and their degree of order. N-14 and H-1-DOSY NMR probe the dynamics and mobility of soluble species. In a dense gel, on the other side, Al-27- and Si-29-(MAS) NMR elucidate the varying local connectivity between initial nano-objects and the final solid products. It has been found that cylindrical micelles control the transformation of solubilized silica and alumina during the formation of zeolite nuclei and guide their crystal growth to nano-Beta rods with bimodal mesoporosity. The predominant smaller mesopores (6 to 8 nm) originate from the template’s hydrophobic alkyl chains, while larger mesopores (10 to 30 nm) are supposed to result from a spinodal decomposition-type segregation of phases consisting of as-formed hydrophobic zeolite rods and an aqueous solution.

Rational molecular design of anion exchange membranes functionalized with alicyclic quaternary ammonium cations

High alkaline stability is critical for polymeric anion exchange membranes (AEMs) and ionomers for use in alkaline electrochemical energy conversion and storage devices such as fuel cells, electrolyzer cells and advanced batteries. Here, we have prepared and studied ether-free polyfluorenes tethered with N,N-dimethylpiperidinium (DMP) and 6-azonia-spiro[5.5]undecane (ASU) cations, respectively, attached through heteroatom-free alkyl spacers. By employing alkyl-alkyl Suzuki cross-coupling, these alicyclic quaternary ammonium cations are attached at the 4-position to impede ionic loss. Thus, all the beta-hydrogens sensitive to elimination reactions are placed in strain-free rings able to fully relax by the spacer flexibility. Consequently, the AEM carrying DMP cations shows a very high alkaline and thermal stability, retaining more than 91% of the cations after 2400 h immersion in 2 M NaOH at 90 degrees C. Compared with corresponding AEM functionalized with N-alkyl-N-methylpiperidinium (AMP) cations [conventionally tethered via the 1(N)-position], the ionic loss by beta-elimination is successfully reduced by up to 92%. The AEM functionalized with DMP also reaches a high hydroxide conductivity of 124 mS cm(-1) at 80 degrees C. Consequently, tethering piperidine-based cations via the 4-position instead of the 1(N)-position results in AEMs with substantially improved thermal and alkaline stability, combined with high hydroxide conductivity.

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 3056-33-5. Quality Control of N2,9-Diacetylguanine.
