摘要

The stability of the keto-heterocyclic ring permits the use of chlorosulfoiiic acid as a, means of deaminating the exocyclic methylsulfamyl group. This treatment, followed by ammonia, leads to V, and hydrolytic ring-opening gives VT I The formation of a 3-ketobenzothiadiazine ring to protect a methylsulfamyl group against, attack by chlorosulfonic acid suffers from one dieadvantage: a vigorous hydrolysis is necessary to regenerate the open-ring compound. ...
