title: Gold-catalyzed ring-expansion through acyl migration to afford furan-fused polycyclic compounds.
abstract: A gold-catalyzed ring-expansion reaction of alkynones to access furan-fused polycyclic compounds is reported. Mechanistic studies revealed that the reaction might occur through a tandem 1,2-acyl migration/Friedel-Crafts reaction.
