Product Details of 16400-32-1. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 1-Bromo-2-pentyne, is researched, Molecular C5H7Br, CAS is 16400-32-1, about Palladium-Catalyzed Decarboxylative Generation and Propargylation of 2-Azaallyl Anions. Author is Tang, Shaojian; Wei, Wenjing; Yin, Dan; Poznik, Michal; Chruma, Jason J..

A palladium-catalyzed decarboxylative propargylation (DcPg) of propargyl 2,2-diphenylglycinate imines was developed for the synthesis of [((diphenylmethylene)amino)alkynyl]arenes (Ph2)C=NCH(Ar)CH2C≡CR [R = Me, Et, TMS; Ar = 4-CNC6H4, 2-BrC6H4, 3-pyridyl, etc.]. In this process, the nature of the propargyl ester and aryl imine components, as well as the catalyst system and solvent had a significant impact on the ratio of desired propargylated products vs. allene and/or diene side products that arose via different modes of C-C bond formation. The resulting propargylated products were transformed readily into useful (Z)-homoallylic amines. Moreover, the regioisomeric diene products could be converted to pharmaceutically-relevant diarylmethyl imines via a two-step Diels-Alder/oxidation process.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Development and validation of an in silico P450 profiler based on pharmacophore models, published in 2006-03-31, which mentions a compound: 27469-61-0, mainly applied to Cytochrome P450 inhibitor pharmacophore model enzyme kinetics, Electric Literature of C17H18Cl2N2.

In today’s drug discovery process, the very early consideration of ADME properties is aimed at a reduction of drug candidate drop out rate in later development stages. A part from in vitro testing, in silico methods are evaluated as complementary screening tools for compounds with unfavorable ADME attributes. Especially members of the cytochrome P 450 (P 450) enzyme superfamily. e.g. P 450 1A2, P 450 2C9, P 450 2C19, P 450 2D6, and P 450 3A4, contribute to xenobiotic metabolism, and compound interaction with one of these enzymes is therefore critically evaluated. Pharmacophore models are widely used to identify common features amongst ligands for any target. In this study, both structure-based and ligand-based models for prominent drug-metabolizing members of the P 450 family were generated employing the software packages LigandScout and Catalyst. Essential chem. ligand features for substrate and inhibitor activity for all five P 450 enzymes investigated were determined and analyzed. Finally, a collection of 11 pharmacophores for substrates and inhibitors was evaluated as an in silico P 450 profiling tool that could be used for early ADME estimation of new chem. entities.

A copper-free intramol. azide-alkyne cycloaddition reaction of 4-hydroxymethyl-β-lactam with sodium azide was described. The present approach involves the incorporation of an alkyne moiety through O-alkynylation of 3-hydroxy β-lactam with various propargylic halides. The generality of the method was demonstrated by treating the corresponding tosylates or mesylates of the hydroxymethyl functionality of a variety of β-lactam-tethered terminal and internal alkynes with sodium azide in a one-pot three-step reaction to furnish novel oxazepane-β-lactam fused triazole scaffolds of diverse interest in good yield.
