Triflic anhydride-promoted cyclization of sulfides: A convenient synthesis of fused sulfur heterocycles

A new approach to the synthesis of annulated sulfur heterocycles based on triflic anhydride-promoted cyclization of the hetaryl(aryl) containing alkyl sulfides was elaborated. Smooth demethylation of initially formed cyclic sulfonium salts by treatment with triethylamine afforded a number of five-, six- and seven-membered fused sulfur heterocycles. Unexpected ring opening took place in the reaction of diethylamine with 5-membered sulfonium salts.
