Microwave-assisted copper(i) catalyzed A3 cascade coupling of imidazo[1,2-a]pyridines via C–H bond functionalization as selective COX-2 inhibitors and antioxidants, and in silico studies

Abstract

A proficient copper(i) catalyzed one pot synthetic protocol has been established to synthesize medicinally essential substituted imidazo[1,2-a]pyridines via C–H bond amination followed by acetylene incorporation under microwave irradiation.
