Copper(I) catalyzes a regioselective asymmetric allylation of ketones with commercially available 1,4-pentadiene as a pronucleophile to provide a variety of chiral tertiary alcohols bearing a terminal (Z)-1,3-diene in high (Z)/(E) ratio and high enantioselectivity. The synthetic utility of the product is demonstrated by a copper(I)-catalyzed regioselective borylation of the 1,3-diene group.
