It was found that itaconitin, a yellow coloring matter of a mould Aspergillus itaconicus KINOSHITA, possesses a 3,5-dienoic acid system which is converted into an aromatic ring by the action of acetic anhydride to give acetylanhydroitaconitin. Oxidation of hexahydroitaconitin with potassium permanganate, as well as the ozonolysis of the same substance yielded 2-methylnonanedioic acid. From these and other experimental data including nuclear magnetic resonance spectra, the structural formula of itaconitin and all its derivatives hitherto prepared were conclusively established.
