An efficient and highly enantioselectivecopper‐catalyzed allylic alkylation of disubstituted allyl halides with primary and secondary organolithium reagents using phosphoramidite ligands is reported. The use of trisubstituted allyl bromides allows, for the first time, the enantioselective synthesis of all‐carbon quaternary stereogenic centers with these reactive organometallic reagents.
