The present invention relates to cinchona-based bifunctional organocatalysts and methods for preparing chiral hemiesters using the same. More specifically, the present invention relates to methods for preparing chiral hemiesters from prochiral or meso cyclic acid anhydrides via desymmetrization, using birunctional cinchona alkaloid catalysts comprising sulfonamide functional groups.
