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

A novel method for annulating furans to ketones, involving treatment of the dichlorocarbene adduct of the derived methyl enol ether with base, has been exploited in the synthesis of the title natural product 1 from the known trans-decalone 2.
