✦ Synopsis

Basic treatment In methanol of linearly condensed 1,3-benzothiazinedichloro-&lactam 1 led to a 1,4-benzothiazepi 2, a tetraaubetituted isoquinoline 2, and a thiazole &sulfide derivative 4 via a new ring transformation. The structure of the thiazola disulfide 4 was determined by X-ray diffraotion.
