Process for producing optically active 2-hydroxybutyric ester |
| abstract |
To provide a process for producing an optically active 2-hydroxybutyric ester at high yield and high optical purity. n The process for producing an optically active 2-hydroxybutyric ester (1), characterized in that the process includes reacting an optically active 2,3-epoxypropionic ester (2) with a methyl Grignard reagent CH 3 MgX (wherein X represents a halogen atom) in the presence of a copper catalyst in an amount of 0.05 to 0.5 mol with respect to 1 mol of (2) through the following scheme:n n(wherein R represents a C1 to C6 alkyl group or a C7 or C8 aralkyl group; X represents a halogen atom; and * represents S- or R-absolute configuration). |
