Title:
キラルホスフィン、その遷移金属錯体および不斉反応でのその使用
Document Type and Number:
Japanese Patent JP4947866
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 chiral C1-C6 TunaPhos ligands. The ruthenium TunaPhos complex reduces ketones to the corresponding alcohols with 95-99.6% enantioselectivity. The transition metal complexes of the chiral ligands are useful in asymmetric reactions such as asymmetric hydrogenation, hydride transfer, hydrosilylation, hydroboration, hydrovinylation, hydroformylation, hydrocarboxylation, isomerization, allylic alkylation, cyclopropanation, Diels-Alder reaction, Heck reaction, isomerization, Aldol reaction, Michael addition and epoxidation reactions.
