Abstract
A one-pot, multicomponent reaction enables the transformation of commercial aryl amines, aldehydes, and azides into valuable benzimidazole structural units with wide substrate scope and diversity via an efficient copper-catalyzed amination of N-aryl imines, in which imine acts as a directing group by chelating to the metal center.
