stereoselective asymmetric directcross-aldolreactionbetween aliphatic aldehydes and α-chloroaldehydes has been developed as a method for the formation of the sole cross-aldol adduct with both enantio- and diastereocontrol, and either anti- or syn-aldol adducts were obtained in good to excellent stereoselectivities by use of proline or a novel axiallychiralaminosulfonamide as catalyst.
