A new type of nucleophile, a 3-imino nitrile carbanion generated in situ by Thorpe reaction of acetonitrile with a base, was developed successfully and applied in a Pd-catalyzed asymmetric allylic alkylation with mono-substituted allyl reagents under Pd/SIOCPhox catalysis, affording β-enaminonitrile products in high yields with excellent regio- and enantioselectivities.
