摘要:

将手性二茂铁双膦配体ImiFerroPhos应用到β-取代-α,β-不饱和磷酸酯的不对称氢化反应中,在温和的反应条件下,以高收率及较高对映选择性合成了一系列β-取代的手性磷酸酯,最高获得了92%的ee值.

Abstract:

A series of chiral ferrocenyl diphosphine ligands (ImiFerroPhos ligands) has been applied to the hydrogenation of β-substituted α,β-unsaturated phosphonates to generate a range of optically active β-substituted alkylphosphonates in good yields with good enantioselectivity (up to 92% ee) under mild reaction conditions.

Key words: β-Substituted α,β-unsaturated phosphonate, Asymmetric catalytic hydrogenation, ImiFerroPhos ligands, Rhodium (Ⅱ) complex, Chiral β-substituted alkylphosphonate
