New modular P-chiralligands 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-catalyzedasymmetrichydrogenation of functionalized olefins.

Chiral diphosphites and diphosphoramidites derived from BINOL or diphenylprolinol are efficient ligands in asymmetricRh-catalyzed olefin hydrogenation, provided the proper achiral backbone is chosen.
