reported that incorporates an N-sulfinyl amide in place of the carboxylic acid of proline to serve as a hydrogen bond donor, chiral directing group, and solubilizing element. The successful application of this type of catalyst to the asymmetricaldolreaction of acetone and aryl aldehydes, for which proline performs poorly, is also described.
