A copper-catalyzed enantioselective hydroboration of α,β-unsaturated aldehydes with pinacolborane provides the corresponding γ-pinacolboronate alcohols in good yields and enantioselectivities through consecutive hydroboration of the C=O and C=C bonds. The resulting γ-pinacolboronate alcohols could be utilized in various transformations.
