| titleOfInvention | Method for preparing glutamic acid derivatives and pyroglutamic acid derivatives and new production intermediates |
| abstract | The 4-protected hydroxypyroglutamic acid derivative was alkylated with an alkylating agent, a 4-protected hydroxy-4-alkyl glutamic acid derivative was obtained, and then subjected to hydrolysis and deprotection of the protecting group to prepare a glutamic acid derivative represented by monatin. How to. 4-protected hydroxypyroglutamic acid derivatives can be readily prepared from hydroxyproline. In addition, 4-protected hydroxypyroglutamic acid derivatives are alkylated at the 4-position selectively, stereoselectively, and can be easily converted to glutamic acid derivatives after alkylation, and thus are particularly suitable for efficiently preparing monatin with high optical purity. Can be used. |
