Facile synthesis of 1, 2-benzisothiazole-3-one-1,1-dioxide methylsulfonyl derivatives

An improved and general synthesis of saccharin methylthio and methylsulfone derivatives from chloro-substituted saccharins is presented. A large-scale procedure for preparation of chloro-substituted saccharins was developed. Treatment of the saccharin chlorides with sodium thiomethoxide and t-BuOK in DMF gave the saccharin methyl sulfides, which upon chromium(VI) oxide catalyzed oxidation with periodic acid afforded the corresponding saccharin methylsulfones in high yields.
