Two new oxidation products of dihydrousnic acid, III and IV were assumed to be 3-acetyl-5-methylcyclopentane-1, 2, 4-trione and α-acetyl-γ-methylteronic acid by the chemical and spectral evidences, respectively. The mechanism of the formation III and IV from dihydrousnic acid was discussed.
通过化学和光谱证据,推测二氢萘酸的两种新氧化产物 III 和 IV 分别为 3-乙酰基-5-甲基环戊烷-1,2,4-三酮和α-乙酰基-γ-甲基三酮酸。讨论了从二氢吡啶甲酸生成 III 和 IV 的机理。
