Benzyl and t-butyl sulfoxides as sulfenyl halide equivalents: A convenient preparation of benzisothiazolones

Article abstract of DOI:10.1016/0040-4039(92)88037-6

A new methodology is described for the synthesis of benzisothiazolones from benzylsulfinyl or t-butylsulfinyl substituted carboxamides that provides a mild alternative to conventional cyclization methods that employ halogens.
