A series of chiral bisphosphine ligands were designed and synthesized based on single-handed quinoline oligoamide foldamers. The bisphosphine ligands can coordinate with Rh(cod)BF in a 1 : 1 stoichiometry and the resulted chiral Rh(i) catalysts were applied in the asymmetric hydrogenation of α-dehydroamino acid esters, in which excellent conversions and promising levels of enantioselectivity were achieved.
基于单手性喹啉寡酰胺折叠体,设计并合成了一系列手性双膦配体。双膦配体可以与 Rh(cod)BF 以 1:1 的化学计量比配位,得到的手性 Rh(i)催化剂被应用于α-去氢氨基酸酯的不对称氢化反应中,获得了优异的转化率和良好的对映选择性。
