A new approach to the synthesis of annulated sulfur heterocycles based on triflic anhydride-promoted cyclization of the hetaryl(aryl) containing alkylsulfides 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
