Turned by gold: The gold (I) -catalyzed enantioselective hydroalkoxylation of allenes proceeded rapidly to give useful oxygen heterocycles in high yields and with high stereoselectivity. The procedure was also effective for the cyclization of γ-hydroxyallenes that possess an axially chiral allenyl moiety and for the cyclization of δ-hydroxyallenes.
