Copper-Catalyzed Synthesis of a Novel Fused-Ring Heterocyclic Systems BearingStructurally-Diverse Benzazoles

A new operationally-simple ultrasonic-assisted process involving CuI-catalyzed intra-molecular C-Hactivation of benzothiazole, benzoxazole, and benzimidazole to construct an array of functionalized fused-ringheterocyclic compounds has been developed. Structural confirmation of the final products became possible byusing a combination of different methods like chemical enrichment, spectroscopy, and elemental analysis.
