摘要:

报道了三[(S)-α,α-二(4-甲基苯基)-2-吡咯烷甲醇]膦酰胺催化剂催化链状酮酯化合物的不对称还原反应。 研究发现,该方法对碳链长为5~11的链状酮酯具有较好的催化效果,在物质的量分数为5%手性膦酰胺催化作用下,产物手性羟基酯化合物的收率最高可达89%,对映体过量(ee)值最高可达95%。 此方法为手性链状羟基酯衍生物的合成提供了新选择。

Abstract:

The asymmetric reduction of chain aliphatic ketoesters catalyzed by tris[(S)?α,α?bis(4-methylphenyl)-2-pyrrolidine methanol]phosphonamide was reported. The protocol displays good catalytic efficiency for the chain ketoesters with the carbon number of 5-11. With the presence of molar fraction 5% of the chiral phosphonamide catalyst, the yield of the chiral hydroxy esters is up to 89% and the enantionmeric excesses (ee) value is up to 95%. This method provides an alternative option for the synthesis of chiral γ- or δ- hydroxy esters.

Key words: Ketoesters, Hydroxy esters, Chiral phosphonamide, Asymmetric reduction
