1,2,4-Trisubstituted chiral homoallylic alcohols are valuable intermediates in natural product synthesis and complex molecular architectures; however, their catalytic asymmetric synthesis remains challenging due to the need for precise control of regioselectivity, diastereoselectivity, E/Z geometry, and enantioselectivity. Herein, we report a palladium-catalyzed enantiospecific three-component reaction of aldehydes, borylated allyl acetates, and dimethylzinc for the efficient synthesis of 1,2,4-trisubstituted anti-(Z)-homoallylic alcohols. The present method employs readily accessible chiral borylated allyl acetates and proceeds with high levels of stereochemical control, providing a practical approach to structurally complex homoallylic alcohols.
