The reaction of ozonolysis peroxide products of (+)-α and (+)-β-pinenes with Fe(III) salts in MeOH was studied. It was found that decomposition of methoxyhydroperoxides obtained via ozonolysis of (+)-β-pinene using FeCl3⋅6H2O occurred at room temperature with formation of nopinone and its 3-chloro derivative; under reflux, nopinone and p-isopropylphenol. Replacing FeCl3⋅6H2O by Fe(NO3)3⋅9H2O produced the single product nopinone. Decomposition of peroxide compounds obtained via ozonolysis of (+)-α-pinene using FeCl3⋅6H2O gave a mixture of (1S,3S)-3-acetyl-2,2-dimethyl-1-(2,2-dimethoxyethyl)cyclobutane and [(1S,3S)-3-acetyl-2,2-dimethylcyclobutyl]acetate.
研究了在 MeOH 中 (+)-α 和 (+)-β蒎烯的臭氧分解过氧化物产物与 Fe(III) 盐的反应。研究发现,通过使用 FeCl3⋅6H2O 臭氧分解 (+)-β蒎烯得到的甲氧基氢过氧化物在室温下发生分解,生成壬酮及其 3-氯衍生物;在回流条件下,生成壬酮和对异丙基苯酚。用 Fe(NO3)3-9H2O代替 FeCl3-6H2O,可生成单一产物莨菪酮。通过使用 FeCl3⋅6H2O 对 (+)-α蒎烯进行臭氧分解而得到的过氧化物进行分解,得到了(1S,3S)-3-乙酰基-2,2-二甲基-1-(2,2-二甲氧基乙基)环丁烷和[(1S,3S)-3-乙酰基-2,2-二甲基环丁基]乙酸酯的混合物。
