Abstract: Acetylene gas isan important feedstock for chemical production,although it is underutilized in organic synthesis. We have developedan intermolecular gold(I)-catalyzed alkyne/alkene reaction of o-allylphenols with acetylene gas that gives rise to chromanesby a stereospecific aryloxycyclization through the nucleophilic regioselectiveopening of cyclopropyl gold(I)-carbene intermediates. The syntheticapplication of this method was demonstrated in the late-stage functionalizationof the natural product lapachol.
