Abstract:
A chiral hydrogenated H8-BINOL bisphosphine compound is provided, with the structure shown as the following formula (I), wherein both R1 and R2 are halogen, H or C1-C10 aliphatic group; R3 is H or C1-C10 aliphatic group; R4 is halogen, amino, nitro, H, C1-C10 aliphatic group or C1-C10 aromatic group; and X is phenyl, substituted phenyl, cyclohexyl, substituted cyclohexyl, C6-C30 aromatic group, or C6-C30 heterocyclic aromatic group containing one or more heteroatoms selected from N, S, O. The present invention further provides a catalyst for an asymmetric catalytic hydrogenation reaction which contains the compound, wherein the catalyst can produce more than 90% of enantiomers and efficiency with the turnover number of greater than 100,000 in the asymmetric hydrogenation reaction of imines.
