| titleOfInvention | Method for preparing chiral 4-substituted-3-hydroxybutyric acid and salts thereof |
| abstract | The present invention relates to a process for the preparation of chiral 4-substituted-3-hydroxybutyric acid and salts thereof, and more particularly to the chiral center of (S) -3-activated hydroxybutyrolactone as a raw material. The present invention relates to a method for economically preparing chiral 4-substituted-3-hydroxybutyric acid represented by Formula 1 and salts thereof.n n n n n n n n n n In Formula 1 above:n n n X represents a hydrogen atom, a halogen atom, -OH, -SR ', -CN, -N 3 , -NR a R b R c or -OAr, wherein R' represents an aliphatic or aromatic hydrocarbon, R a , R b and R c are the same as or different from each other and represent a hydrogen atom, an alkyl group having 2 to 5 carbon atoms, or a benzyl group, and Ar represents a phenyl group, an alkoxyphenyl group or a naphthyl group. |
