  摘要：

  Treatment of a wide range of functionalized hydroxyallenic esters with 5 mol % Ph3PAuCl and 5 mol % AgOTf in CH2Cl2 at 25 degrees C for l h produced selectively 2-alkyl- and aryl-3-ethoxycarbony1-2,5-dihydrofurans in good to excellent yield through intramolecular hydroalkoxylation by a 5-endo mode.

  Ethyl alpha-(1-hydroxy-1-alkyl)methylallenoates and alpha-(1-hydroxy-1-aryl)methylallenoates containing not only electron-donating groups but also an electron-withdrawing group on the aryl group at the alpha-position have been shown to undergo an efficient and selective copper-catalyzed intramolecular hydroalkoxylation to give functionalized 3-ethoxycarbony1-2-alkyl- and -aryl-2,5-dihydrofurans in good to excellent yields through a 5-endo mode.
