A novel ferrocene‐based P‐stereogenic diphospine ligand series dubbed JDayPhos was developed, which rhodium(I) complexes of some of its members exhibited excellent enantioselectivity (up to >99% ee) and high activity in asymmetric hydrogenation of β‐unsubstituted or ‐substituted itaconates and α‐methylene‐γ‐oxo‐carboxylates.
开发了一种新型的基于二茂铁的P-立体异构二膦配体系列JDayPhos,该化合物的一些成员的铑(I)配合物表现出出色的对映选择性(高达> 99%ee),并且在β-未取代或-β的不对称氢化中表现出高活性。取代的衣康酸酯和α-亚甲基-γ-氧代羧酸酯。
