A rapid access to highly substituted phenanthrenyl ketones through gold-catalyzedcyclization of 1,6-diyn-4-en-3-ols with furans has been developed. Gold catalysts are effective to catalyze three cascade processes involving Friedel–Crafts/furan-ynecyclization/heteroenynemetathesis through CO bond and alkyne activation. This method offers several advantages such as high selectivities and easily accessible
