On the Synthesis of 3,4-Dihydro-2H-1,2-benzothiazine 1,1-Dioxides

The 3,4-dihydro-2H-1,2-benzothiazine 1,1-dioxides were prepared by reduction of the corresponding 1,2-benzothiazin-2-ones with diborane.The latter were obtained by the action of primary amines on 4,5-dimethoxy-2-carbomethoxymethylbenzenesulfonyl chloride
