Method of preparing (R)-4-amino-3-hydroxybutyric acid |
| abstract |
(R)-4-amino-3-hydroxybutyric acid is prepared from the hydrochloride of the methyl ester or ethyl ester of (2S, 4R)-4-hydroxyproline via the intermediary stages of the corresponding, non-isolated (R)-4-hydroxy-1-pyrroline-2-carboxylic acid ester and the isolated (R)-4-hydroxy-2-pyrrolidone. The (R)-4-amino-3-hydroxybutyric acid which is useful for pharmacological purposes is obtainable in a high yield according to this method. |
