Regiospecific Bi‐Catalysed Domino C‐N/C‐S Bonds Formation: Synthesis of 1,4‐Thiazines/1,4‐Thiomorpholines

Abstract

Abstract A domino Bi‐catalysed C−N/C−S bond formation of N ‐sulfonylaziridines is developed with 1,4‐dithiane‐2,5‐diol to give 3,4‐dihydro‐1,4‐thiazines at room temperature. The use of Bi(OTf) 3 as a catalyst, atom economy and regioselectivity are the important practical features. magnified image
