The present invention relates to the technical field of organic chemistry, specifically an asymmetrical hydrogenation of an α-ketonic acid compound, the technical proposal being as shown by the following formula:
Wherein R1 is a phenyl, a substituted phenyl, a naphthyl, a substituted naphthyl, a C1-C6 alkyl or aralkyl, the substitute is a C1-C6 alkyl, a C1-C6 alkoxy, a halogen, the number of the substituents is 1-3.
M is a chiral spiro-pyridyl amido phosphine ligand iridium complex having the following structure,
Wherein, R is hydrogen, 3-methyl, 4-tBu or 6-methyl.
本发明涉及有机化学技术领域,特别是一种α-酮酸化合物的不对称氢化,其技术方案如下式所示:
其中 R1 为苯基、取代苯基、萘基、取代萘基、C1-C6 烷基或芳烷基,取代基为 C1-C6 烷基、C1-C6 烷氧基、卤素,取代基的数目为 1-3。
M 是具有以下结构的手性螺吡啶氨基膦配体铱络合物、
其中,R 是氢、3-甲基、4-tBu 或 6-甲基。
