single organic catalyst that transforms readily accessible racemic monosubstituted succinic anhydrides into synthetically valuable chiral succinate mono esters in high enantiomeric excesses. We recently discovered that modified cinchona alkaloids are highly effective chiral Lewis base catalysts for desymmetrization of cyclic anhydrides. 7,8 In view of the synthetic utility of optically active monosubstituted
