A direct and highly enantioselective rhodium-catalyzed allylicalkylation of allyl benzoate with α-substituted benzyl nitrile pronucleophiles is described. This simple protocol provides a new approach toward the synthesis of acyclic quaternary carbon stereogenic centers and provides the firstexample of the direct asymmetricalkylation of a nitrile anion. The synthetic utility of the nitrile products
