[reaction: see text] A facile preparation of chiral alpha-aryloxy carboxylic acids via asymmetrichydrogenation of the corresponding unsaturated acids has been discovered. A number of catalysts have been identified that give high product enantioselectivity, and the scope of the reaction has been examined with respect to substitution on the aromatic ring and olefin.
