Abstract:New modular P-chiral ligands have been prepared from commercially available (S)-α,α-diphenylprolinol. With these new types of ligands, up to 95% ee was achieved in the Rh-catalyzed asymmetric hydrogenation of functionalized olefins.
Keywords:Asymmetric reactions   Phosphorus ligands   Rhodium   Hydrogenation
