A class of trinuclear N-fused hybrid scaffolds was constructed by transition metal-freeC(sp2)-N coupling and cyclization of 2-(2-bromoaryl)- or 2-(2-bromovinyl)benzimidazoles with 2-methoxy- or 2-aryloxybenzimidazoles under microwave irradiation.
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
通过铜催化的多米诺加成/双环化反应,已经开发了一种高效且通用的新型多环苯并咪唑衍生物的组装方法。由双-(邻-卤代芳基)碳二亚胺成功地组装了多种可用作合成药物和功能材料的多环苯并咪唑衍生物。意外的N-甲基化的苯并[4,5]咪唑并[1,2- a ]吲哚也可以被选择性地组装。在这些多米诺骨牌过程中,多键和多环部分很容易在一个锅中形成。
