Title

New Experimental Conditions for Tandem hydroalumination/Cu-Catalyzed Asymmetric Conjugate Additions to β-Substituted Cyclic Enones

Abstract Readily available alkenylalanes, arising from hydroalumination of unprotected terminal alkynes, have been directly employed for the copper-catalyzed asymmetric conjugate addition (ACA) to β-substituted cyclic enones. The desired products, containing a quaternary stereogenic center, are generally obtained in good yields and enantioselectivities.
