efficient copper-catalyzed amination of N-aryl imines is described. This one-pot, multicomponent reaction, in which imine acts as a directing group by chelating to the metal center, affords a potential route for the transformation of the commercial aryl amines, aldehydes, and azides into valuable benzimidazole structural units with wide substrate scope and diversity. The synthetic and mechanistic aspects
描述了新颖和有效的铜催化的N-芳基亚胺的胺化。这种单锅多组分反应(其中亚胺通过与金属中心的螯合而充当导向基团)提供了潜在的途径,可将商业化的芳基胺,醛和叠氮化物转化为有价值的苯并咪唑结构单元,具有广泛的底物范围和多样性。提出了综合和机制方面。
