- Benzisothiazol-3-ones through a Metal-Free Intramolecular N–S Bond Formation
-
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.
