Oxazepines and thiazepines. 41 . Synthesis of 4‐aryl‐2,3‐dihydro‐2‐styryl‐1,5‐benzothiazepines by the reaction of (E,E)‐cinnamylideneacetophenones with 2‐aminothiophenol and their conversion into 2,2‐disubstituted 3‐acetyl‐2,3‐dihydrobezothiazoles

摘要: New 4-aryl-2,3-dihydro-2-styryl-1,5-benzothiazepines 8–13 have been synthesized by an acid catalyzed reaction of 2-arninothiophenol (1) and (E,E)-cinnamylideneacetophenones 2–7. Ring contraction 1,5-benzothiazepines provided 2,2-disubstituted 3-acetyl-2,3-dihydrobenzothiazoles 14–19 under acetylating conditions.
