Article abstract of DOI:10.1016/S0040-4020(01)85933-0

Controlled potential oxidation of a variety of substituted o-toluenesulfonamides at a Pt anode in MeCN using a divided cell provides 3-methyl-4,5-dihydro-1,2,4-benzothiadiazepine-1,1-dioxides selectively and in generally good yields.The scope and limitations of this one-step heterocyclization sequence are also discussed.
