摘要：

The optical yields of the enantio-differentiating hydrogenation of aromatic β-ketoesters over tartaric acid-modified Raney nickel were found to be lower than those of aliphatic γ-ketoesters when the aromatic group is conjugated to the ketone moiety. The reason for the reduced optical yield is due to the lower intrinsic enantio-differentiation compared to the aliphatic substrate.
