Abstract

This invention relates to a process for preparing an optically active 2-arylpropionic acid of general formula (I), by the hydrogenation, in a heterogeneous aqueous-organic medium, of a 2-arylacrylic acid of general formula (II) in the presence of a catalyst consisting of a rhodium derivative and a water-soluble chiral ligand. In the general formulae (I) and (II), Ar represents an optionally substituted monocyclic or polycyclic aromatic radical or an optionally substituted aromatic heterocyclic radical: ##STR1##
