Process for producing enantiopure β-amino acid derivatives corresponding to general formula (I) R1-NZ-CHR2—CH
2
—COOR3 (I) in which R1 and R2 independently denote organic residues optionally forming a cyclic substituent, R3 denotes H or an organic residue, and Z represents H or an amino function-protecting group, comprising a step in which a mixture of enantiomers of a compound corresponding to general formula (II) R1-NZ-CHR2—CH
2
—COOR4 (II) in which R1, R2 and Z are as defined for formula (I), and R4 is an organic residue, is subjected to hydrolysis in the presence of a lipase.
