The RuPHOX-Ru catalyzed asymmetric hydrogenation of β-imide ketones to afford chiral γ-primary amino alcoholsis is reported. Under the optimal reaction conditions (using Na2CO3 as a base, EtOH as a solvent), a series of β-imide ketones were hydrogenated in the presence of RuPHOX-Ru and H2 (5.0 MPa) to give the desired products with excellent yields and enantioselectivities (quantitative conversions and up to 98% ee). The hydrogenated products were characterized by NMR and HRMS, and their absolute configuration was also confirmed. The current procedure provides a concise and efficient synthesis of chiral γ-primary amino alcohols.
