Gold(I)-catalyzed formation of furans by a Claisen-type rearrangement of ynenyl allyl ethers

Abstract

A series of ynenyl allyl ethers were rearranged into polysubstituted furans in the presence of a gold(I) catalyst. It is proposed that the transformation involves a Claisen-type rearrangement that allows the efficient creation of quaternary centers under mild experimental conditions.
