A two-step sequence for the enantio- and diastereoselective synthesis of exclusively alkyl-substituted acyclic allylic systems with a stereocenter in the allylic position is reported. The asymmetric induction and the site selectivity are controlled in an enantio- and regioconvergent nickel-catalyzed C(sp(3))-C(sp(3)) cross-coupling of regioisomeric mixtures of racemic alpha-/gamma-silylated allylic halides and primary alkylzinc reagents. The silyl group steers the allylic displacement towards the formation of the vinylsilane regioisomer, and the resulting C(sp(2))-Si bond serves as a linchpin for the installation of various C(sp(3)) substituents in a subsequent step.
