The invention relates to novel organo phosphorus P-chiral optically active compounds of formula (I) having a hydroxyl, mercapto, amino, carboxyl, sulfonyl group on aryl near a phosphorus atom, to the preparation and the use thereof in then asymmetrical catalysis of unsaturated compounds. Novel acylphosphine optically pure ligands embodied in the form of transition metal complexes exhibit an increased activity and enantloselectivity, in particular in asymmetrical hydrogenation, in comparison with the same type Uganda such as DiPAMP.
该发明涉及具有化学式(I)的新型有机磷P-手性光学活性化合物,其在含磷原子附近的芳基上具有羟基、巯基、氨基、羧基、磺酰基基团,以及其在不对称催化不饱和化合物中的制备和使用。新型酰基膦光学纯配体以过渡金属配合物的形式体现,与同类型的乌干达化合物(如DiPAMP)相比,在不对称氢化等反应中表现出增强的活性和对映选择性。
