The structure of magnoline and magnolamine, two alkaloids from the leaves of Magnolia fuscata, were reexamined. The tentative structure of dauricine type, proposed by Proskurnina, was examined through oxidation product of the two alkaloids, magnolamic acid, or dimethoxydiphenyl ether-dicarboxylic acid. For its determination, 2, 3-dimethoxy-diphenyl ether-5, 4′-dicarboxylic, 2, 6-dimethoxydiphenyl ether-4, 4′-dicarboxylic acids were synthesized but neither compound coincided with magnolamic acid.
