Abstract

Basic treatment in methanol of linearly condensed 1,3-benzothiazinedichloro-β-lactam 1 led to a 1,4-benzothiazepine 2, a tetrasubstituted isoquinoline 3, and a thiazole disulfide derivative 4 via a new ring transformation. The structure of the thiazole disulfide 4 was determined by X-ray diffraction.
