Note on the Synthesis, Properties, and Reactions of 4-Methoxy-2-phenyl-1,5-benzothiazepine
Hofmann, Hans,Fischer, Herbert,Bremer, Matthias
, p. 2087 - 2089 (2007/10/02)
The title compound 3 is synthesized by O-alkylation of the corresponding lactam 1.The behaviour of 3 is different from a compound with the same formula which has been published recently in this journal; the structure of 3 therefore was confirmed by X-ray
Rearrangements and Complex Eliminations with 1,5-Benzothiazepin-4-ones
Kaupp, Gerd,Gruendken, Eleonore,Matthies, Doris
, p. 3109 - 3120 (2007/10/02)
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.
