Abstract A facile synthesis of various 2-(carbazolyl)benzothiazoles has been developed by one-pot CuBr-catalyzed three-component reactions of 2-iodoanilines, arylaldehydes, and elemental sulfur. Unlike traditional approach, this reaction exhibited a good functional group tolerance to produce the corresponding 2-(carbazolyl)benzothiazoles in good yields in the absence of any additive.
