Highly effective asymmetric hydrogenation of β-ketophosphonates in the presence of Ru–(S)-SunPhos as catalyst was realized; good to excellent enantioselectivities (up to 99.9% ee) and excellent diastereoselectivities (96:4) were obtained.
在Ru-(S)-SunPhos催化剂存在下实现了β-酮膦酸酯的高效不对称加氢。获得了良好至优异的对映选择性(高达99.9%ee)和优异的非对映选择性(96:4)。
