The highly efficient synthesis of benzoisothiazol-3-ones from thiobenzamides has been described with good functional group compatibility and excellent yields. This work represents the first example of selectfluor-promoted N–S bond formation processes. This method provides a facile approach to access various important bioactive benzoisothiazol-3-ones.
An umpolung sulfoxide reagent as α-hydroxy and α-chloro benzyl carbanion equivalents

ortho-[(N-Methyl)carbamoyl]phenyl benzyl sulfoxide is used as a synthetic equivalent of α-hydroxy and α-chloro benzyl carbanions by means of a two-step sequence involving (1) highly stereoselective α-C-alkylation with alkyl bromides, and (2) displacement of the sulfinyl group by an OH or a Cl under Pummerer or chloro-Pummerer conditions, respectively. The sulfinyl auxiliary can be effectively regenerated and recycled.
