• Oxidation of methyl 9,10-dioxodeisopropylallodehydroabietate (II) with alkaline hydrogen peroxide yielded a dicarboxylic acid (III). Thermal decomposition of the tricarboxylic acid (IV) obtained by saponification of (III) afforded two kinds of fluorenone derivatives, (VII), m. p. 147〜149°, and (VIII), m. p. 130〜131°. Structures of these compounds were examined, together with the Beckmann rearrangement of the oxime of (VIII).
