In order to confirm the assumed structural formula of coriaria dilactone, derived from coriamyrtin by aromatization with hydriodic acid and oxidation, methylmagnesium iodide was applied to benzene-1, 2, 3, 4-tetracarboxylic acid dianhydride and the objective lactone was obtained. Since its potash fusion yielded phthalic acid, it was clarified that coriaria dilactone was different from the formula assumed earlier and that the gem-dimethyl groups were found to be present in a symmetrical position. These results have confirmed the fact that both coriaria lactone and coriaric acid are isomers of the structural formulae assumed previously.
