A process for the resolution of enantiomeric mixtures of a chiral carboxylic acid, including an esterification reaction of the carboxylic acid in an organic solvent, in the presence of a stereoselective hydrolase, characterized in that an orthoester of the formula R<SUP>1</SUP>-C(OR<SUP>2</SUP>)<SUB>3</SUB>, in which R<SUP>1 </SUP>is selected from H and C<SUB>1</SUB>-C<SUB>4</SUB>alkyl and R<SUP>2 </SUP>is C<SUB>1</SUB>-C<SUB>8</SUB>alkyl or -CH<SUB>2</SUB>-C<SUB>6-10</SUB>aryl, is used as the esterification reactive. |
