Abstract

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.
