A ligand-free copper-catalyzed tandem azide-alkyne cycloaddition (CuAAC), Ullmann-type C-N coupling, and intramolecular direct arylation has been described. The designed strategy resulted in the synthesis of a novel trazole-fused azaheterocycle framework. The reaction gave good yields (59-77%) of 1,2,3-triazole-fused imidazo[1,2-a]pyridines in a single step.
