We successfully extended our Rh/bisphosphine-thiourea (ZhaoPhos) catalytic system to asymmetric hydrogenation of alpha,beta-unsaturated N-acylpyrazoles affording products with high yields and excellent enantioselectivities (up to 97% yield, 99% ee). The pyrazole moiety played an important role in providing H-bond acceptor sites, which is critical for achieving high reactivities and enantioselectivities.
