Abstract

The asymmetric transfer hydrogenation (ATH) of a series of γ-aryl-α,γ-dioxo-butyric acid esters has been accomplished smoothly. Six ferrocene-based chiral ligands have been prepared and applied in the reactions respectively. Simultaneously, enantiopure Ts-DPEN's utilization in the ATH also has been investigated and the products were obtained in 30–85% chemical yields with 37–95.5% ee.
