An economic and practical transformation from secondary alkyl-substituted propargyl acetates to a variety of nucleophilic substitution products was described. This reaction was catalyzed by inexpensive InCl3. High yields and excellent chemoselectivity were obtained. The five-, six-, and seven-membered propargyl cycloethers were also successfully constructed by this protocol.
