  • Synthesis of 1,2-disubstituted benzimidazoles through DDQ-oxidized intramolecular dehydrogenative coupling of N,N′-dialkyl o-phenylenediamines
    作者:Youcai Ma、Ruimei Xiong、Yangyang Feng、Xiaohui Zhang、Yan Xiong

    日期:2020.10
    which starts from N,N′-dialkyl o-phenylenediamines via intramolecular dehydrogenative coupling under the oxidation of DDQ with mild conditions. Through detailed optimization of reaction conditions, only DDQ was found essential without any additives to reach to the highest yield of 99%. In the cases of linear aliphatic substituents, the synthesis of 1-alkyl-2-phenylbenzimidazoles showed high selectivities
    已经开发了1,2-二取代的苯并咪唑的合成方法,该方法从N,N'-二烷基邻苯二胺开始,在温和的条件下,通过DDQ的分子内脱氢偶联作用。通过详细优化反应条件,发现只有DDQ才是必需的,而无需添加任何添加剂即可达到99%的最高收率。在直链脂族取代基的情况下,1-烷基-2-苯基苯并咪唑的合成显示出高选择性,并且通过2D NMR COZY相关分析鉴定了它们的结构。提出了一种合理的机制来解释观察到的反应性和选择性。

  • Copper-Mediated Synthesis of Substituted 2-Aryl-<i>N</i>-benzylbenzimidazoles and 2-Arylbenzoxazoles via C–H Functionalization/C–N/C–O Bond Formation
    作者:Murali Mohan Guru、Md Ashif Ali、Tharmalingam Punniyamurthy
    DOI:10.1021/jo2005632
    日期:2011.7.1
    An efficient method for the transformation of N-benzyl bisarylhydrazones and bisaryloxime ethers to functionalized 2-aryl-N-benzylbenzimidazoles and 2-arylbenzoxazoles is described. The protocol involves a copper(II)-mediated cascade C-H functionalization/C-N/C-O bond formation under neutral conditions. Substrates having either electron-donating or -withdrawing substituents undergo the cyclization to afford the target heterocycles at moderate temperature.
