摘要：

The 2‐methyl‐2H‐1,2‐benzothiazin‐4‐(3H)‐one 1,1 dioxide (2), obtained according to a new, one‐pot method, is transformed into the pyrrolidino enamine 3. Reaction of p‐toluenesulphonyl azide with 3 gives, via an unstable triazoline adduct which loses nitrogen, the two isomeric tosylamino derivatives 4 and 5. The structures have been assigned by exhaustive nmr analysis and some aspects on their formation and chemical behaviour are discussed. Copyright © 1990 Journal of Heterocyclic Chemistry
