Elemental sulfur mediated synthesis of benzoxazoles, benzothiazoles and quinoxalines via decarboxylative coupling of 2-hydroxy/mercapto/amino-anilines with cinnamic acids
An easy and practical method has been developed for the synthesis of 2-benzylbenzoxazoles and 2-benzylbenzothiazoles using sulfur mediated decarboxylativecoupling of cinnamic acids with 2-hydroxyanilines and 2-mercaptoanilines respectively under metal- and solvent-free conditions. However, the reaction of 2-aminoanilines with cinnamic acids leads to the formation of 2-arylquinoxalines under the same
We have developed a photoredox/Cu dual catalyzed enantioselective remote cyanation via1,4-heteroarylmigration. Experimental and computational studies have been carried out to reveal the reaction mechanism and explain the origins of the regio- and enantioselectivities of the remote cyanation process. This methodology exhibits mild conditions, a broad substrate scope and good regio- and enantioselectivities
