✦ Synopsis


H and 13C chemical shifts are reported for the condensation products of l-amino-2-phenylazonaphthalene-4-sulphonic acid with benzaldehyde and trans-cinnamaldehyde, two model compounds for sweetening agents. Assignments, based on several two-dimensional techniques, confirm the naphthimidazole skeleton for both compounds.
