NEW APPROACHES TO THE ASYMMETRIC SYNTHESIS OF NON-PROTEINOGENIC α-AMINO ACIDS AND DIPEPTIDES THROUGH CHIRAL β-LACTAM INTERMEDIATES

Novel and effective routes to optically pute 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 cycloadditions of ketenes to imines.
