A convenient and efficient method for the synthesis of polysubstituted indenes has been developed by the iron(III) trichloride-catalyzed tandem mono- and dibenzylation/cyclization reactions of benzylicalcohols with alkynes. This method is featured with the easily available starting materials, cheap catalyst, simple manipulation and mild conditions.
