mediates. — The reactive zinc enolate derived from the N-protected glycine ester (I) is used as nucleophile in Pd-catalyzed allylic alkylation reaction. In general, (Z)-allylic substrates give rise to anti/syn-π-allyl Pd-complexes which react regioselectively at the anti-position. — (KAZMAIER*, U.; POHLMAN, M.; Synlett 2004, 4, 623-626; Fachrichtung Org.
