Document Type and Number:
Japanese Patent JP4837857
Kind Code:
B2
Abstract:
Chiral ligands and transition metal complexes based on such chiral ligands useful in asymmetric catalysis are disclosed. The chiral ligands include phospholanes, P,N ligands, N,N ligands, biphenols, and chelating phosphines. The ferrocene-based irridium (R,R)-f-binaphane complex reduces imines to the corresponding amines with 95-99.6% enantioselectivity and reduces beta-substituted-alpha-arylenamides with 95% enantioselectivity.The transition metal complexes of the chiral ligands are useful in asymmetric reactions such as asymmetric hydrogenation of imines, asymmetric hydride transfer reactions, hydrosilylation, hydroboration, hydrovinylation, hydroformylation, allylic alkylation, cyclopropanation, Diels-Alder reaction, Heck reaction, isomerization, Aldol reaction, Michael addition and epoxidation reactions.
