[GRAPHICS]The kinetic resolution of epoxides with phenols catalyzed by a polymer supported Co(salen) complex is applied to the first enantioselective catalytic synthesis of parallel libraries, The corresponding 1-aryloxy-2-alcohols are obtained in high yield, purity, and enantiomeric excess. Further elaboration with diversity elements provides highly efficient access to important classes of pharmacologically active compounds.
