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.

An efficient and convenient copper-catalyzed oxidative chalcogenation of benzothiazoles and imidazo[1,2- a ]pyridines with sulfur/selenium powder and aryl boronic acids was developed. This procedure allows access to a wide range of structurally diverse arylchalcogen-substituted benzothiazoles/imidazo[1,2- a ]pyridines in good yields and with good functional group tolerance. A biological evaluation revealed that some of the obtained products exhibited in vitro antiproliferative activities on human-derived lung, stomach, esophageal, and breast cancer cell lines.

An efficient approach to sulfenyl imidazoheterocycles has been developed via iodine-triphenylphosphine mediated direct sulfenylation of imidazoheterocycles with sodium sulfinates. The reactions proceed smoothly under transition-metal-free conditions with a broad range of substrate scope, giving the desired products in moderate to excellent yields. This journal is
