  • Title: Facile preparation of 3-substituted benzisothiazoles from o-mercaptoacylphenones.
    Author: Devarie-Baez NO, Xian M.
    Journal: Org Lett; 2010 Feb 19; 12(4):752-4. PubMed ID: 20078088.
    Abstract:
    A synthesis of 3-substituted benzisothiazoles starting from readily available o-mercaptoacylphenones is presented. The key cyclization step features a mild S-nitrosation and its succeeding intramolecular aza-Wittig reaction leading to the construction of the title compounds.
