| titleOfInvention | Process for producing either optically active n-substituted .beta.-amino acid and optically active n-substituted .beta.-amino acid ester or optically active n-substituted 2-homopipecolic acid and optically active n-substituted 2-homopipecolic acid ester |
| abstract | A process in which a racemic mixture of an N-substituted .szlig.-amino acid alkyl ester or N-substituted 2-homopipecolic acid ester represented by the general formula (I): (I) (wherein Ar, R1, R2, R3, R4, and R5 are as defined in the description) is subjected to selective hydrolysis of only either of the enantiomers in the presence of a hydrolase to yield an optically active, N- substituted ((R) or (S))-.szlig.-amino acid or optically active, N-substitut ed ((R) or (S))-2-homopipecolic acid represented by the general formula (II): (II) and simultaneously obtain the unreacted, optically active, N-substitute d ((S) or (R))-.szlig.-amino acid alkyl ester or unreacted, optically active, N- substituted ((S) or (R))-2-homopipecolic acid ester represented by the gener al formula (III): (III) which has the absolute configuration opposite to that o f the compound represented by the general formula (II). |
