Abstract
A series of sulfides was successfully synthesized by a thiol-disulfide exchange reaction using disulfides as the reactive substance. After cleavage of S-S bonds by ammonium thioglycolate catalysis, Michael addition reactions were performed using various acceptors in one-pot. The catalyzed-reaction mechanism has been discussed based on the by-products. In addition, 2,3H-1,5- benzothiazepines were also successfully synthesized from 2,3H-1,5-benzothiazepine-4(5H)-one with satisfactory yields using Lawesson’s reagent.
Keywords: Ammonium thioglycolate, benzothiazepine, sulfide, synthesis.
