DuanPhos has been proved to be the most effective ligand for this reaction. The high yield and enantioselectivity of the asymmetric hydrogenation of the α-ketone enol acetates represents a feasible synthetic route to important pharmaceutical building blocks: α-hydroxy ketones.
                                    对于α-酮烯醇
乙酸酯的催化不对称氢化,已经观察到高对映选择性(高达99%ee)。已证明DuanPhos是该反应最有效的
配体。α-酮烯醇
乙酸酯的不对称氢化的高收率和对映选择性代表了通往重要药物结构单元:α-羟基酮的可行合成途径。
