| titleOfInvention | Optically active 2-hydroxy-4-phenyl butyric acid and production of ester of same butyric acid |
| abstract | PURPOSE: To make possible to industrially produce the subject optically active compound useful as a synthetic raw material of various medicinal drugs by subjecting optically active 2-hydroxy-4-phenyl-3-butenic acid to hydrogenation in the presence of a solvent and further esterifying, as desired. n CONSTITUTION: Optically active 2-hydroxy-4-phenyl-3-butenic acid is subjected to hydrogenation in a suitable solvent such as ethyl acetate or a mixed solvent of methanol and toluene in the presence of a suitable catalyst such as palladium- carbon at a temperature of, e.g. 0-300°C, preferably 10-70°C under a pressure of from normal pressure to 200kg/cm 2 , preferably under normal pressure according to a well-known method of usual catalytic hydrogenation reaction in a heterogeneous system to industrially advantageously obtain optically active 2-hydroxy-4-phenyl butyric acid. Next, said acid is esterified by using an alcohol corresponding to the aimed compound in a usual method to industrially advantageously obtain the aimed optically active 2-hydroxy-4-phenyl butyric acid alkyl ester. n COPYRIGHT: (C)1991,JPO&Japio |
