摘要: A diastereo- and enantioselective aldol reaction between aldehydes a synthetically useful ketomalonate 1c as hydrated form was developed, either anti- or syn-aldol adducts having chiral tetrasubstituted carbon center were obtained in high enantioselectivities by use of tetrazole analogue L-proline (S)-2 an axially amino sulfonamide (S)-3 catalyst.
