Technical Notes: 1.A chiral diphosphine ligand used in the highly-enantioselective hydrogenation of ketoesters, hydroxyketones, ketophosphonates and succinates. 2.A ligand used for the dynamic kinetic resolution of at,ß- unsaturated lactones via asymmetric copper catalyzed conjugate reduction. 3.Used in the intramolecular Heck reaction for the synthesis of diterpenoids. 4.Used in asymmetric P auson-Khand reaction. 5.Used in asymmetric iminonitroso Diels-Alder re action. 6.Palladium catalyzed asymmetric hydrogenation of N-tosyl ketimines References: 1.Tetrahedron L ett., 2003, 44, 823. 2.Angew.
