2,3‐Dihydro‐1,5‐benzothiazepine‐4(5H)‐thiones 13‐22 were prepared by the reaction of the appropriate 2,3‐dihydro‐1,5‐benzothiazepin‐4(5H)‐ones with Lawesson's reagent. N‐Acyl (23‐25) and N‐alkyl (26‐28) derivatives have also been synthesized. Oxidation with 3‐chloroperoxybenzoic acid afforded sulfoxides 29‐32, and sulfones 33‐40 were obtained by using H2O2 as an oxidizing agent.
