Abstract
The invention concerns a method for preparing α-phenylalanine ester with substantially enantiomeric purity of formulae (I) and (II) wherein Alk represents a linear or branched C1-C6 alkyl radical, characterized in that it consists in contacting a mixture of α-phenylalanine ester enantiomers with a lipase, a protease or an esterase.
Claims7
Method for preparing substantially enantiomerically pure α-phenylalanine esters of formula (I) or (II):
- in which Alk represents a linear or branched alkyl radical containing from 1 to 6 carbon atoms, wherein a mixture of enantiomers of α-phenylalanine esters is brought into contact with a protease or an esterase.
