摘要

An efficient and facile electrophilic iodocyclization for the synthesis of various O-, N-, and S- containing dihaloheterocycles has been developed. A wide range of the substituted propargyl alcohols having–OH,–NTs, and–SAc functional groups reacted with molecular iodine or bromoiodine at ambient temperature to produce the corresponding dihalogenated O-, N-, and S-containing five-and six-membered heterocycles in good to high yields; ...
