摘要:
愈创蓝油烯在 85 °C 在 N,N-二甲基甲酰胺-0.5 M 硫酸中或在 25–35 °C 在滤纸表面上自动氧化,与其他产物一起产生两种标题化合物,它们在平衡并构成在许多天青烃的自氧化过程中经常观察到的分子间一碳转移反应的重要中间体。

Autoxidation of guaiazulene either at 85 °C in N,N-dimethylformamide-0.5 M sulfuric acid or at 25–35 °C on the surface of a filter paper yielded, together with other products, the two title compounds which were shown to be in equilibrium and to constitute important intermediates for the intermolecular one-carbon transfer reactions frequently observed during autoxidation of many azulenic hydrocarbons.
