Gold-catalyzed intermolecular reaction of 2-(1-alkynyl)-2-alken-1-ones with diarylethenes to construct polysubstituted cyclopenta[c]furans through a cascade heterocyclization/[3+2] cycloaddition sequence

A method for preparing polysubstituted cyclopenta[c]furans from 2-(1-alkynyl)-2-alken-1-ones and diarylethenes via gold catalysis is reported. The reaction shows good regioselectivity to afford the desired product in moderate to excellent yields.
