Substituted 2H-1,3-benzothiazines and 2,3-dihydro-1,4-benzothiazepines react with dimethyl acetylenedicarboxylate in aqueous methanol to give new, unexpected condensed-skeleton heterocycles. The structures of the new compounds were determined by 1H and 13C nuclear magnetic resonance (NMR), two-dimensional (2D) heteronuclear multiple-bond correlation (HMBC), infrared (IR), and for one derivative also by X-ray analysis.
