Alkaline permanganate oxidation of hinokiic acid yielded a crystalline dicarboxylic acid, C11H18(COOH)2, and a ketonic acid, C11H18(COCH3)COOH. These acids, and the products obtained on further oxidative degradation, proved identical with the products of ozonolysis of hinokiic acid. From the results of experiments as outlined in these papers, the author proposed a constitution formula of hinokiic acid (cf. Figs.).
