Abstract
Acylation of 2-amino-4-chlorobenzenesulfonamide by 2-acetoxyisobutyryl chloride under acidic conditions unexpectedly gave 6-chloro-3-methyl-4H-1,2,4-benzothiadiazine 1,1-dioxide and 8-ehloro-2,2,3a-trimethyl-3a,4-dihydrooxazolo[2,3-b] [1,2,4]benzothiadiazin-1-one 5,5-dioxide, the skeletons of which incorporate the carbon atom of the acetoxyl carbonyl group of the acid chloride.
