Syntheses of 1,5-benzothiazepines: Part V - Synthesis of 2-carboxy-2,3-dihydro-4-(p-tolyl)-8-substituted-1,5-benzothiazepines
β-(p-Toluoyl)acrylic acid (2) reacts with 5-substituted 2-aminothiophenols (1a-e) in ethanol containing gl. acetic acid to give 2-carboxy-2,3-dihydro-4-(p-tolyl)-8-substituted-1,5-benzothiazepines (3a-e) in satisfactory yields.Their structure elucidation is based on elemental analyses and IR, PMR and mass spectral data.
