    Synthesis and in vitro antibacterial activity of oxazolidine LBM-415 analogs as peptide deformylase inhibitors
    摘要:
    The drug resistant bacteria pose a severe threat to human health. The increasing resistance of those pathogens to traditional antibacterial therapy renders the identification of new antibacterial agents with novel antibacterial mechanisms an urgent need. In this study, a series of (2S)-N-substituted-1-[(formyhydroxyamino) methyl]-1-oxohexyl]-2-oxazolidinecarboxamides were designed, synthesized and evaluated for in vitro antibacterial activity. Most of these compounds displayed good activities against Gram-positive organisms comparable to reference agent LBM-415. Crown Copyright (C) 2010 Published by Elsevier Ltd. All rights reserved.

  • Nitration of α,β-unsaturated esters. Evidence for positive charge build-up adjacent to carbonyl carbon
    作者:Stuart A. Hewlins、John A. Murphy、Jian Lin、David E. Hibbs、Michael B. Hursthouse
    DOI:10.1039/a607170h
    日期:——
    Reactive intermediates formed in the nitration of certain α,β-unsaturated esters with nitronium tetrafluoroborate exhibit behaviour expected of highly reactive α-carbonyl cations. Three diagnostic reaction types have been observed which indicate the presence of these destabilised cations: (i) trapping in a Ritter reaction, (ii) cyclopropane formation from propyl cations, (iii) Wagner–Meerwein migration of alkyl groups. Semi-empirical calculations of the relative gas-phase stabilities of the proposed intermediate cations are useful in rationalising the observed chemistry.
    在用四氟硼酸亚硝酰进行某些α,β-不饱和酯的硝化反应中形成的活性中间体表现出高度活性α-羰基阳离子的预期行为。已观察到三种诊断性的反应类型,表明这些不稳定的阳离子的存在:(i)在Ritter反应中捕获,(ii)从丙基阳离子形成环丙烷,(iii)烷基的Wagner-Meerwein迁移。对所提出的中间阳离子的相对气相稳定性的半经验计算有助于合理化观察到的化学现象。
  • Enantioselective hydrogenation of α,β-unsaturated acids. Substrate-modifier interaction over cinchonidine modified

    DOI:10.1016/s0957-4166(97)00526-0
    日期:1997.11
    X-Ray diffraction, IR measurements and catalytic hydrogenation of various substituted acrylic acids in apolar solvents, as well as molecular modelling provide new insight into the nature of the cinchonidine-substrate interaction and a general rule to predict the major enantiomer.
    X射线衍射,IR测量和非极性溶剂中各种取代丙烯酸的催化加氢以及分子建模,为新奇可尼定与底物相互作用的性质提供了新的见识,并为预测主要对映异构体提供了一般规则。
