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.
2,3 - 二氢 - 1,5 - 苯并噻嗪 - 4 (5H) - 硫酮 13-22 通过适当的 2,3 - 二氢 - 1,5 - 苯并噻嗪 - 4 (5H) - 酮与劳森试剂反应制备. N-酰基(23-25)和N-烷基(26-28)衍生物也已合成。用3-氯过氧苯甲酸氧化得到亚砜29-32,以H2O2为氧化剂得到砜33-40。
