The present invention relates to an improved process for the preparation of phenolic carboxylic acid derivatives catalysed by biocatalytic esterification, transesterification or amidation of a corresponding lower alkyl ester. Biocatalysis is performed in the presence of suitable enzymes, e.g. hydrolases, especially esterases, amidases, lipases and proteases.

La présente invention concerne un procédé amélioré de préparation de dérivés d'acide carboxylique phénolique catalysés par estérification biocatalytique, transestérification ou amidation d'un ester alkylique inférieur correspondant. La biocatalyse est réalisée en présence d'enzymes appropriées, par exemple, des hydrolases, notamment, des estérases, des amidases, des lipases et des protéases.
