An air‐stable, simple (RP)‐mentylbenzylphosphinate, readilyavailable in large quantities, can efficiently induce the rhodium‐catalyzed asymmetrichydrogenation of α‐acetamidocinnamates with high enantioselectivity (up to 99.6 % ee). Intramolecular hydrogen bonding plays an important role in this asymmetric induction.
