An efficient and versatile method for the assembly of novel polycyclic benzimidazole derivatives has been developed by Cu-catalyzed domino addition/double cyclization reactions. A wide variety of polycyclic benzimidazole derivatives, which might be used as synthetic medicines and functional materials, were successfully assembled from bis-(o-haloaryl)carbodiimides. Unexpected N-methylated benzo[4,5]imidazo[1,2-a]indoles can also be selectively assembled. Multibonds and polycyclic moieties were conveniently formed in one pot during these domino processes.
一种高效、通用的新型多环苯并咪唑衍生物的组装方法，通过 Cu 催化的多步加成/双环化反应得以实现。多种多环苯并咪唑衍生物，可用作合成药物和功能材料，成功地由双（邻卤代芳基）碳二亚胺组装而成。同时，也可选择性地组装出意想不到的 N-甲基苯并[4,5]咪唑并[1,2-a]吲哚。这些多步反应中，多键和多环片段可以在一锅反应中方便地形成。
