CD spectra of the analogs of aromatic DNP-α-amino acids and the related N-DNP-arylalkylamines, in which the positions of the two chromophoric groups were exchanged with each other, were studied.The analogs, in which the DNP-amino group is separated from the asymmetric carbon, did not show any marked Cotton effect near 400 nm, indicating the importance of direct attachment of the DNP-NH group to the chiral carbon atom for showing the characteristic CD spectra of N-DNP-aromatic α-amino acids.
