One Pot Synthesis of C3-Sulfurized Imidazolo [1,2-a] Pyridines

Abstract

A facile and efficient annulation strategy was developed from easily accessible a-bromoketones, aminopyridines and benzazol, which afforded a series of imidazole [1,2-a]pyridine sulfides in moderate to good yields. The reaction involves the formation of C−N/C−S bond with the advantages of easy operation and wide substrates scope.
