A method to prepare 3-alkoxyindanones efficiently by gold-catalyzedtandemcycloisomerization/Petasis–Ferrier rearrangement from ortho-ethynylarylaldehydes with alcohols is described. The reaction was accomplished in moderate to excellent yields under mild reaction conditions and also offers a convenient synthetic route to 3-alkoxycyclopentenones.
