Abstract

Abstract A new copper-catalyzed oxidative cyclization via C [BOND] H amination between 2- aminopyridines and methyl aryl/heteroaryl ketones has been developed under ambient air. Imidazo [1, 2-a] pyridines containing a wide range of functional groups have been synthesized from basic and easily available starting materials. This simple, one-pot reaction protocol is applicable for the direct preparation of zolimidine (a marketed antiulcer drug) ...
