The thallium(III) nitrate-oxidation of 2-alkoxy-5-hydroxytropones gave, in good yields, the mono- and diacetals of tropoquinones, which can be used for the introduction of oxygen functions to the seven-membered nucleus and preparation of the substituted tropoquinones. An improved synthesis of 4-methyl-p-tropoquinone or 4-methoxy-p-tropoquinone was accomplished.
