  • Synthesis of functionalized benzimidazoles and quinoxalines catalyzed by sodium hexafluorophosphate bound Amberlite resin in aqueous medium
    作者:Pranab Ghosh、Amitava Mandal
    DOI:10.1016/j.tetlet.2012.09.045
    日期:2012.11
    for the selective synthesis of 1,2-disubstituted benzimidazoles and quinoxalines in water–methanol (1:1) mixture with the aid of resin bound hexafluorophosphate ion as catalyst is reported. The method is also effective for the incorporation of quinoxaline nucleus at the A ring of pentacyclic triterpenoid, friedelin. A plausible mechanism for the formation of disubstituted benzimidazole has also been suggested

  • 1,2-Disubstituted Benzimidazoles by the Iron Catalyzed Cross-Dehydrogenative Coupling of Isomeric <i>o</i>-Phenylenediamine Substrates
    作者:Pawan Thapa、Philip M. Palacios、Tam Tran、Brad S. Pierce、Frank W. Foss

    Benzimidazoles are common in nature, medicines, and materials. Numerous strategies for preparing 2-arylbenzimidazoles exist. In this work, 1,2-disubstituted benzimidazoles were prepared from various mono- and disubstituted ortho-phenylenediamines (OPD) by iron-catalyzed oxidative coupling. Specifically, O2 and FeCl3·6H2O catalyzed the cross-dehydrogenative coupling and aromatization of diarylmethyl
    苯并咪唑在自然界,药物和材料中很常见。存在制备2-芳基苯并咪唑的许多策略。在这项工作中,通过铁催化的氧化偶联,由各种单取代和二取代的邻苯二胺(OPD)制备1,2-二取代的苯并咪唑。具体而言,O 2和FeCl 3·6H 2 O催化二芳基甲基和二烷基苯并咪唑前体的交叉脱氢偶联和芳构化。N,N′-二取代-OPD底物比其N,N-二取代的异构体具有更高的反应活性,这似乎与其相对于与Fe3 +络合和电荷转移的倾向有关。该反应还将N-单取代的OPD底物转化为2-取代的苯并咪唑。然而,贫电子底物通过分子间亚氨基转移产生1,2-二取代的苯并咪唑。动能 试剂和光谱学(紫外可见和EPR)研究表明,这种机制涉及金属-底物的络合,电荷转移和有氧转化,涉及高价Fe(IV)中间体。总的来说,证明了比较可持续和有效合成1,2-二取代苯并咪唑的比较策略。

    DOI:10.1016/j.tetlet.2011.05.142
    日期:2011.8
    We described herein the use of glycerol as solvent in the catalyst-free synthesis of benzodiazepines and benzimidazoles. This simple and efficient method furnishes the corresponding 1-H-1,5-benzodiazepines and 1,2-disubstituted benzimidazoles in good yields by the condensation of o-phenylenediamine with several ketones and aldehydes, respectively. In addition, glycerol can be easily re-utilized for
    我们在本文中描述了在无催化剂的苯并二氮杂卓和苯并咪唑的合成中甘油作为溶剂的用途。这种简单而有效的方法通过邻苯二胺分别与几种酮和醛缩合,以高收率提供了相应的1 - H -1,5-苯并二氮杂卓和1,2-二取代的苯并咪唑。另外,甘油可以容易地重新用于进一步的缩合反应多达四次而不会失去活性。

    Silica phenyl sulfonic acid (SPSA) was prepared and effectively used in the one‐pot synthesis of 2‐aryl‐1‐arylmethyl‐1H‐1,3‐benzimidazoles from o‐phenylenediamine with aldehydes in water in the presence of tetrabutyl ammonium bromide with good to high yield. Also, SPSA was used as a catalyst for the synthesis of bis(indolyl)methanes in water. J. Heterocyclic Chem., (2011).
