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
