    Anti-tubercular agents. Part 7: A new class of diarylpyrrole–oxazolidinone conjugates as antimycobacterial agents
    摘要:
    In an effort to discover new anti-tubercular agents, a series of new diarylpyrrole oxazolidinone conjugates have been designed and synthesized. The anti-tubercular activity of these new conjugates (4a-n and 5a-d) against Mycobacterium tuberculosis H(37)Rv and drug resistance strains such as M. tuberculosis Rif(R) and M. tuberculosis XDR are discussed, wherein compound 4i has been found to be the most potent amongst the series. MTT assay was performed on the active conjugates of the series (4b-f, 4i and 5c) against mouse macrophage (J-774) cells to evaluate cytotoxic effects and selective index values. In addition, these conjugates (4a-n and 5a-d) are also tested against a panel of Gram-positive and Gram-negative bacterial strains. The docking studies have been carried out to provide some insight into the mechanism of action for this class of compounds. (C) 2013 Published by Elsevier Masson SAS.

  • Nonclassical Mechanism in the Cyclodehydration of Diols Catalyzed by a Bifunctional Iridium Complex
    作者:Greco González Miera、Aitor Bermejo López、Elisa Martínez‐Castro、Per‐Ola Norrby、Belén Martín‐Matute
    DOI:10.1002/chem.201805460

    1,4‐ and 1,5‐diols undergo cyclodehydration upon treatment with cationic N‐heterocyclic carbene (NHC)–IrIII complexes to give tetrahydrofurans and tetrahydropyrans, respectively. The mechanism was investigated, and a metal‐hydride‐driven pathway was proposed for all substrates, except for very electron‐rich ones. This contrasts with the well‐established classical pathways that involve nucleophilic
    1,4-和1,5-二醇在用阳离子N-杂环卡宾(NHC)-Ir III络合物处理后发生环化脱水,分别生成四氢呋喃和四氢吡喃。研究了该机制,并提出了一种适用于所有底物的金属氢化物驱动途径,除了电子非常丰富的底物。这与涉及亲核取代的成熟经典途径形成对比。

    Acyl radicals are invaluable intermediates in organic synthesis, however their generation remains challenging. Herein, we present an unprecedented light‐driven, cobalt‐catalysed method for the generation of acyl radicals from readily available 2‐S‐pyridyl thioesters. The synthetic potential of this methodology was demonstrated in the Giese‐type acylation of activated olefins in the presence of heptamethyl
    酰基是有机合成中不可估量的中间体,但是它们的产生仍然具有挑战性。本文中,我们提出了一种空前的光驱动,钴催化的方法,用于从易于获得的2- S-吡啶基硫代酯中生成酰基自由基。该方法的合成潜力已在庚二酸七甲酯存在下活化烯烃的Giese型酰化反应中得到了证明。这种维生素B 12衍生物被证明是研究过程中最有效的催化剂。所开发的方法具有广泛的底物范围(38个示例),良好的官能团耐受性和温和的反应条件。此外,它易于扩展(在20倍的放大过程中进行了说明),从而可以进行准备性使用。机理研究表明,该反应通过自由基途径进行,关键步骤涉及酰基维生素B 12络合物的形成以及随后的Co-C键光解。
