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.

The phochemical reactions of α,β-acetylenic ketones have been examined.Irradiation of 1-p-substituted phenyl-2-propyn-1-ones 2-4 in primary alcohols gave 2,5-disubstituted furans 2a-4c.The formation of furans can be explained in terms of cyclization, foll
