A series of enantiomerically pure γ-heteroatom substituted β-hydroxy esters were synthesized with high enantioselectivities (up to 99.1% ee) by hydrogenation of γ-heteroatom substituted β-keto esters in the presence of Ru-(S)-SunPhos catalyst. These asymmetric hydrogenations provide key building blocks for a variety of naturally occurring and biologically active compounds.
在Ru- (S)-SunPhos催化剂存在下,通过氢化γ-杂原子取代的β-酮酯,合成了一系列具有高对映选择性(高达99.1%ee)的对映体纯的γ-杂原子取代的β-羟基酯。这些不对称氢化为各种天然存在的生物活性化合物提供了重要的组成部分。
