摘要：

The application of the planar chiral [2.2]PHANEPHOS ligand in the Ru(II)-catalyzed asymmetric hydrogenation of beta-ketoesters gave up to 96% ee involving a practical and reproducible procedure using the defined and readily prepared [2.2]PHANEPHOS-Ru(II)bis(trifluoroacetate) salt in the presence of a halide source.
