| titleOfInvention | Process for producing glutamic acid derivative and pyroglutamic acid derivative, and novel production intermediate |
| abstract | After alkylating a 4-protected hydroxypyroglutamic acid derivative with an alkylating agent to obtain a 4-protected hydroxy-4-alkylglutamic acid derivative, a hydrolysis and deprotection step of a protecting group is performed, and then a glutamic acid derivative represented by monatin is obtained. How to manufacture. 4-Protected hydroxypyroglutamic acid derivatives can be easily prepared from hydroxyproline. The 4-protected hydroxypyroglutamic acid derivative is selectively and stereoselectively alkylated at the 4-position, and can be easily converted to a glutamic acid derivative after alkylation, so that monatin with particularly high optical purity is efficiently produced. Therefore, it can be used suitably. |
