very good yields to mono- and bis-α-aminophosphonic acid dialkylesters containing the free phenolic hydroxyl group in a strategic position of the aromatic ring in order to enhance complexation with metal ions. This synthetic procedure is based on the addition of a solution of sodium dialkyl phosphite in phosphite to imine precursors. The addition reaction is highly stereospecific: only one diastereomer
