在膦配位的手性Rh催化剂催化下，前手性烯烃（如双键共轭的羧酸或酰胺）进行对映选择性的氢化的反应。

另外除了Rh催化剂，钛催化的反应也有报道。【Buchwald SL, J Am Chem Soc., 1993, 115, 12569】

反应实例

N-Acetyl-(R)-phenylalanine 2. The rhodium catalyst was obtained by adding (R,R)-DlOP 3 (fromdiethyl tartrarte) to a benzene solution of [RhCl(cyclooctene)2]2 under argon and stirring for 15 min. A solution of the catalyst (1 mmol in EtOH:PhH 4:1) was added under H2 to a solution of

1 (molar ratio catalyst:substrate 1:540). After hydrogenation at 1.1 bar, the solvent was evaporated, the residue was dissolved in 0.5N NaOH and the catalyst was filtered. Acidification and evaporation afforded 2 in 90% yield and 82%ee.
