An efficient enantioselective palladium-catalyzed trifluoromethylated allylic alkylation of N-substituted glycine ethyl esters using α-(trifluoromethyl)alkenyl acetates as trifluoromethyl-containing allyl precursors is established. A series of optically active glycine ethyl ester derivatives containing a trifluoromethylated allyl substituent are readily synthesized in good yields with superior enantioselectivities
