以手性NOBIN(2-氨基-2 '-羟基-1,1'-联萘)为原料,合成了一种新型的杂化磷配体。在铑催化的苯乙烯衍生物和乙酸乙烯酯的不对称氢甲酰化反应中,获得了良好的对映选择性(高达99%ee)。
A new hybrid phosphorus ligand has been prepared starting from chiral NOBIN (2-amino-2'-hydroxy-1,1'-binaphthyl). Excellent enantioselectivities (up to 99% ee) have been achieved in the Rh-catalyzed asymmetric hydroformylations of styrene derivatives and vinyl acetate.
