Opticallypuredipeptides bearing aromatic aminoacid residues were synthesized via homochiral (opticallypure)β-lactams which were obtainedthroughasymmetriccycloadditions of homochiral ketenes to homochiral imines.

Novel and effective routes to optically pure aromatic α-amino acids, α-methyl-α-amino acids and their derivatives including dipeptides are developed via homochiral β-lactams which are obtained through asymmetric [2+2] cycloadditions of ketenes to imines.
