Gold(III)-catalyzed activation of alkynes has been applied for the synthesis of 2,5-disubstituted furans from substituted 5-methoxy-hex-3-yn-2-ols. Mechanistically, the reaction proceeds via an allenyl carbocation intermediate followed by 5-endo-dig cyclization. The high-yielding, open-air, room temperature reaction conditions applied to synthesize a series of alkyl, aryl, and hetero aryl-substituted furans provide uniqueness to the strategy.

A novel and efficient procedure for the synthesis of δ,γ- alkynyl esters by the conjugate addition of alkynylsilanes to acrylate esters in the presence of a catalytic amount of indium(III) chloride has been developed. This method provides a rapid and efficient access to substituted δ,γ-alkynyl esters.

Efficient ring opening of 3,4-epoxyesters with alcohols to produce 4-alkoxy-3-hydroxyesters and their isomerization into 4-ketoesters using boron trifluoride as the catalyst are presented. Both transformations are simple and efficient methods for the synthesis of the above named synthetically useful compounds.
A general and efficient synthesis of substituted furans and dihydrofurans via gold-catalyzed cyclization of (Z)-2-en-4-yn-1-ols

experimental part, p. 1839 - 1845 (2009/06/20)
A highly efficient Au-catalyzed cyclization of (Z)-enynols that proceeds under mild reaction conditions has been developed. This methodology provides rapid access to substituted furans and stereodefined (Z)-5-ylidene-2,5-dihydrofurans in a regioselective
