Copper-catalyzed three-component reaction of imidazo1,2-apyridine with elemental sulfur and arylboronic acid to produce sulfenylimidazo1,2-apyridines

摘要

In this work, an efficient copper-catalyzed three-component reaction for the synthesis of sulfenylimidazo[1,2-a]pyridines using elemental sulfur as the sulfenylating agents has been developed. The reaction could proceed smoothly with a high degree of functional group tolerance and provide the desired products in moderate to good yield.
