L-Homophenylalanine 1, a key intermediate of most commercially important ACE inhibitors, was prepared via catalytic asymmetric hydrogenation of (Z)-2-acetamido-4-phenylcrotonate 3a with a cationic rhodium complex of(1 R,2S)-DPAMPP, followed by acid-hydrolysis of the protecting groups in good yield with >99.9% enantioselectivity.
