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

Synthesis of functionalized furans via gold(I)-catalyzed Claisen-type rearrangement
(Chemical Equation Presented) Gold(I)-catalyzed cyclization of pentenynyl allyl ethers allows the rapid construction of functionalized furans. The concerted oxy-Claisen-type mechanism induces a complete selectivity of the process and allows the easy forma
