A new class of chiral ferrocenyl diphosphine ligands with an imidazole ring, (R(c),S(Fc))-ImiFerroPhos, has been prepared from acylferrocenes through a five-step transformation and successfully applied in the Rh-catalyzed asymmetric hydrogenation of various 3-aryl-substituted 2-phosphonomethylpropenoates, in which a series of chiral 3-phosphono-2-arylmethylpropanoic acid derivatives were achieved in ee values of up to 98%.
一类带有咪唑环的新型手性二茂铁基二膦配体,即(R(c),S(Fc))-ImiFerroPhos,已通过五步转化从酰基二茂铁制备得到,并成功应用于铑催化的各种3-芳基取代的2-膦酰基甲基丙烯酸酯的不对称氢化反应中,由此获得了一系列对映体过量值高达98%的手性3-膦酰基-2-芳基甲基丙酸衍生物。
