We report a novel synthesis of 4-chloro-2-cyclohexyl-6,7-dimethoxy-2H-1,2-benzothiazine-1,1-dioxide 6 from 3,4-dimethoxychalcone 1. Chlorosulfonation of 1 followed by amination, then epoxidation under basic conditions with immediate elimination of the ben

The chalcones (1-10) have been reacted with chlorosulfonic acid to give the corresponding sulfonyl chlorides (1a-10a) (TableI). 3-Methoxychalcone (3) also gave the disulfonyl chloride.The sulfonyl chlorides were reacted with amines and hydrazine to give 4
