The rhodium-catalyzed asymmetric hydrogenation of β-acetylamino acrylonitriles was investigated by using monophosphine and bisphosphine ligands. It was found that an Rh-QuinoxP complex exhibited high enantioselectivities for β-aryl substituted β-acetylamino acrylonitriles and the Rh-JosiPhos CyPF-t-Bu complex was proven to be effective for the hydrogenation of tetrasubstituted olefins from cyclic β-acetylamino acrylonitriles.

(Figure Presented) It takes two to TangPhos: β-Amino acrylonitriles can be readily prepared from acetonitriles. Both of the E/Z isomers undergo hydrogenation with excellent enantioselectivity by using the Rh-TangPhos (TangPhos = l, 1'-ditert-butyl-(2, 2')-diphospholane) catalyst system. The products, chiral β-amino nitriles, are valuable chiral building blocks for many drugs.
