  • Benzimidazole Nitrogen-Directed, Regiocontrolled, Lithiation of Ferrocenyl- and Phenyl-<i>N</i>-<i>n</i>-butylbenzimidazoles

    synthesized to evaluate the influence of the benzimidazole functional group upon their directed lithiation. The regiochemistry of lithiation was studied, as well as the effect of stabilization of the lithiated species by diamine coordination using tetramethyl- ethylenediamine and (−)-sparteine. The lithiations were followed by reaction with a variety of electrophiles to give the disubstituted 2-ferrocenyl-
    2- Ferrocenyl-和2-苯基ñ - ñ -butylbenzimidazoles合成在他们涉及锂化来评估苯并咪唑官能团的影响。研究了锂化的区域化学,以及通过使用四甲基-乙二胺和(-)-天冬氨酸的二胺配位来稳定锂化物种的效果。锂化之后,与多种亲电试剂反应,得到二取代的2-二茂铁基-和2-苯基-N-正丁基苯并咪唑化合物。这项研究表明,尽管简单ñ通过在二茂铁基和苯基上的高度区域控制,可以轻松实现苯并咪唑的正丁基官能化,直接锂化。(-)-Sparteine无法在二茂铁体系中提供不对称诱导作用,其低效率可以通过苯并咪唑氮对锂化物种的分子内配位来解释,这优于Sparteine配位。
  • Synthesis and structure of bifunctional N-alkylbenzimidazole phenylboronate derivatives
    作者:Alexandrea J. Blatch、Olga V. Chetina、Judith A. K. Howard、Leonard G. F. Patrick、Christian A. Smethurst、Andrew Whiting

    N-Methyl and N-n-butyl-2-(2-boronophenyl)benzimidazoles are accessed from the corresponding mono-N-alkyl-ortho-phenylenediamines, either using a polyphosphoric acid-mediated cyclisation with ortho-bromobenzoic acid, or preferably using an Oxone™-mediated cyclisation of the corresponding aldehyde, followed by a lithium-exchange and borylation sequence. The resulting boronic acids show unusual physical and chemical properties, as shown by 11B NMR and X-ray crystallography.
    N-甲基和 N-正丁基-2-(2-硼酸苯基)苯并咪唑是从相应的单 N-烷基正苯二胺中获得的,可以使用聚磷酸介导的与正溴苯甲酸的环化反应,或者最好使用 Oxone™ 介导的相应醛的环化反应,然后进行锂交换和硼酸化反应。如 11B NMR 和 X 射线晶体学所示,生成的硼酸具有不同寻常的物理和化学特性。
