Synthesis of alpha-hydroxyalkyl dehydroazepanes via catalytic enantioselective borylative migration of an enol nonaflate

A Pd-catalyzed borylative migration methodology for cyclic enol perfluorosulfonates was applied to the synthesis of the corresponding 7-membered, azepane ring system. Throughout the optimization, it was shown that the reaction is sensitive to the nitrogen protecting group as well as the type of base and solvent. The resulting cyclic allylboronate reacts stereoselectively with aldehydes for the synthesis of novel alpha-hydroxyalkyl dehydroazepanes in good yield and enantioselectivity over two steps. We highlight the utility of this methodology with an efficient synthesis of the de novo 7-membered ring analogue of the piperidine alkaloid beta-conhydrine. (C) 2018 Elsevier Ltd.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 5570-77-4 is helpful to your research. Formula: C6H12ClN.

Synthesis of some new propanamide derivatives bearing 4-piperidinyl-1,3,4-oxadiazole, and their evaluation as promising anticancer agents

Purpose: To sequentially synthesize piperidine-4-carboxylic acid ethyl ester-appended 1,3,4-oxadiazole hybrids and to evaluate them as anticancer agents. Methods: Ethyl 1-[(4-methylphenyl)sulfonyl]-4-piperidinecarboxylate (1) was synthesized from 4-methylbenzenesulfonylchloride (a) and ethyl 4-piperidinecarboxylate (b) Compound (1) was converted into ethyl 1-[(4-methylphenyl)sulfonyl]-4-piperidine carbohydrazides (2) and 5-{1-[(4-methylphenyl)sulfonyl]-4-piperidinyl}-1,3,4-oxadiazole-2-thiol (3) respectively. A variety of aryl amine (4a-l) were treated with 2-bromopropionylbromide to synthesize an array of propanamide (5a-l). Finally, 5-{1-[(4-methylphenyl)sulfonyl]-4-piperidinyl}-1,3,4-oxadiazole-2-thiol (3) and propanamides (5a-l) were reacted to synthesize target compounds (6a-l) Purity compounds 6a-l was confirmed by spectroscopic techniques like (H-1-NMR), (C-13-NMR) and EI-MS. To determine their anticancer potential, the change in absorbance of mixture and cell line before and after incubation was determined Results: All the compounds 6a-l were successfully synthesized in 73-85 % yield. Compounds 6h, 6j and 6e have low ICso (+/- SD) values of 20 12 +/- 6 20, 10 84 +/- 4 2 and 24 57 +/- 1.62 mu M to act as strong anticancer agents relative to doxorubicin (0.92 +/- 0.1 mu M) used as a reference. Conclusion: The synthesized propanamide derivatives bearing 4-piperidinyl-1,3,4-oxadiazole are potential anticancer agents, but further studies, especially in vivo, are required to ascertain their therapeutic usefulness.

Hydrogen bond mediated partially miscible poly(N-acryloyl piperidine)/poly(acrylic acid) blend with one glass transition temperature

In this work, we have systematically studied the miscibility and phase structure of a hydrogen-bonded polymer blend composed of short rigid poly(N-acryloyl piperidine) (PAP) and long flexible poly(acrylic acid) (PAA). Ultrathin PAP/PAA blend films with various compositions were prepared by solution-casting method. It was found that the spin-coated blend films had distinct surface features with many protuberant domains that can be extracted by toluene. Composition analysis of the isolated protrusion domains and matrix domains revealed that PAP/PAA blend is a partially miscible system with PAP-rich protrusion phase (dispersed phase) and PAA-rich matrix phase. The hydrogen-bonding interaction between the amide carbonyl of PAP and hydroxyl of PAA (O = C center dot center dot center dot H-O) was found to account for the partial miscibility of these two components. Interestingly, only one positively shifted glass transition temperature (T-g) was detected for this blend. This behavior is very different from other reported partially miscible polymer blends, in which two inward shifted TgS are usually observed. Thermal analysis further disclosed that TgS of PAP-rich dispersed phase and PAA-rich matrix phase are very close to each other, thus merged into one broad T-g presented in the blend. The close TgS of these two phases is attributed to the strong hydrogen-bonding interaction between PAP and PAA, which surpasses the compositional difference between them. At high PAP concentrations (above 60 mol percent), the separation of excess PAP in dispersed phase contributed to the appearance of a second T-g that corresponds to that of PAP. Such phase behavior was further confirmed in the free-standing films of PAP/PAA blends.

Neurotoxicity of Prosopis juliflora: from Natural Poisoning to Mechanism of Action of Its Piperidine Alkaloids

Prosopis juliflora was introduced in northeastern Brazil in the 1940s, and since then, it has been available as an alternative for animal nutrition. However, the consumption of P. juliflora as main or sole source of food causes an illness in animals known locally as cara torta disease. Cattle and goats experimentally intoxicated presents neurotoxic damage in the central nervous system. Histologic lesions were mainly characterized by vacuolation and loss of neurons in trigeminal motor nuclei. Furthermore, mitochondrial damage in neurons and gliosis was reported in trigeminal nuclei of intoxicated cattle. Studies, using neural cell cultures, have reproduced the main cellular alterations visualized in cara torta disease and contributed to understanding the mechanism of action piperidine alkaloids, the main neurotoxic compound in P. juliflora leaves and pods. Here, we will present aspects of the biological and toxicological properties of P. juliflora and its pharmacologically active compounds.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 3040-44-6 help many people in the next few years. SDS of cas: 3040-44-6.

Palladium nanoparticles on a pyridinium supported ionic liquid phase: a recyclable and low-leaching palladium catalyst for aminocarbonylation reactions

A new SILP (Supported Ionic Liquid Phase) palladium catalyst was prepared and characterized by(13)C and(29)Si CP MAS NMR, DTG, FTIR and TEM. The presence of the grafted pyridinium cations on the surface of the support was found to result in the formation of highly dispersed Pd nanoparticles with their diameter in the range of 1-2 nm. The catalyst was proved to be active not only in the aminocarbonylation of some model compounds but also in the synthesis of active pharmaceutical ingredients. Catalyst recycling and palladium leaching studies were carried out for the first time in aminocarbonylations leading to CX-546(1-(1,4-benzodioxan-6-ylcarbonyl)piperidine), Moclobemide, Nikethamide and a precursor of Finasteride. The latter reaction proves that not only aryl iodides but also an iodoalkene can be converted into the products with the help of the heterogeneous catalyst. The results show that the conditions should be always fine-tuned in the reactions of different substrates to achieve optimal results. Palladium loss was also observed to depend considerably on the nature of the reaction partners.

In silico investigation of quorum quenching potential of Piper nigrum, Piper betle and Coscinium fenestratum on Vibrio cholerae

Current study investigates the ability of phytoligands to inhibit biofilm formation in multidrug resistant, clinically isolated V. cholerae. Methanolic extracts of Coscinium fenestratum, Piper betle and Piper nigrum were checked for their antibiofilm activity. The herbal bioactive compounds were screened by LC/MS-MS and binding potentials against the drug targets were predicted by molecular docking. The extracts exhibited a MIC in a range of 0.1mg/mL- 0.15mg/mL. Reduction of EPS and rhamnolipids was found to be 84.27%, 67% and 46.6% respectively by C. fenestratum, P. betle and P. nigrum. Six major proteins were selected as putative targets. Of the 6 targets, the phytoligands were effective against AphB, HapR, LuxO and Vps. Berberine present in C. fenestratum (binding energy of -8.6 kcal/mol), Eugenol in P. betle (binding energy – 6.2 kcal/mol) and Piperidine in P. nigrum (binding energy -4.0 kcal/mol) demonstrated effective minimum binding energy against AphB. In silico analysis has revealed that the QS proteins of V. cholerae targeted by the phytoligands might destabilize the biofilm on density dependent manner based on inhibition of surface adhesion and attenuating the virulence factors leading to quorum sensing inhibition. Berberine and Eugenol can be used as quorum inhibitors for attenuation of MDR V. cholerae at sub inhibitory concentration of 50 mu g/mL.
