Abstract
Controlled potential oxidation of a variety of substituted o-to-luenesulfonamides 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.File in questo prodotto:
