A regio- and enantioselective copper-catalyzed 1,4-conjugate addition of trimethylaluminium to linear δ-aryl-substituted α,β,γ,δ-unsaturated alkyl ketones was developed. A series of γ,δ-unsaturated alkyl ketones were obtained in good yields with high regio- and enantioselectivity (up to 88% ee and 96:4 dr). Expansion of the reaction scope to substrates containing aromatic heterocycles also afforded good yields and enantioselectivities (up to 91% ee) with very high regioselectivities, exclusively providing the single 1,4-products.
