  DOI：10.1021/ol801196g

  日期：2008.8.7

  The regio- and chemoselective synthetic method of functionalized alpha-hydroxyalkyl allenic esters was developed from the reactions of various aldehydes with organoindium reagent generated in situ from indium and ethyl 4-bromobutynoate. The alpha-hydroxyalkyl allenic esters possessing electron-donating groups were cyclized to ethyl 2-naphthoate derivatives through intramolecular C-alkylation catalyzed by gold salts.

  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.
