The 1,5-benzothiazepin-4-ones 3, 5, and 7 - 10 are pyrolyzed (with proton catalysis in part).New or rarely documented rearrangements and complex eliminations occur.These are classified and mechanistically discussed.The products and by-products are spectroscopically characterized (IR, UV, NMR, MS).Their configurations are elucidated via photolysis experiments. 4 photodimerizes in solution and in the crystalline state with great ease to give 14. 11 is remarkably insensitive towards hydrolysis.
