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 wi

The heterocyclic bisacylamines 2a-d are solvolyzed to give the 3-propionic acid derivatives 4, 5, and 6 or the heterocycle 1, which may be transformed into 5 by treating 1 with methanol and acids.The pyrolysis of 2 gives 1 by deacylation, the benzothiazoles 7 by elimination and the heterostilbene 9 by elimination.Solvent effects and reaction mechanisms are studied and discussed also in terms of suitable classifications.
