Article abstract of DOI:10.1016/S0957-4166(00)80082-8

Syntheses of new easily accessible chiral alkylarylamidophosphinephosphinite chelating ligands are described. Their rhodium complexes [Rh(L₂*)Cl]₂ are highly effective precursors for the catalytic asymmetric hydrogenation of functionalized ketones. Ketopantoyllactone and N-benzylphenyl glyoxamide are converted to the corresponding alcohols up to 96 and 79.6% ee respectively.
