Oxidation of guaiazulene (1) with peracetic acid in hexane at 25 °C afforded as high as an 80% yield of the title biguaiazulenedione (12), which upon heating at 60 °C under nitrogen gave the title 1-azulenone (13) quantitatively. Oxidation of 12 and 13 was studied under various conditions, and these compounds were shown to be highly important key intermediates for a large number of the complex products obtained by autoxidation of 1.
在己烷中于 25 °C 下用过乙酸氧化愈创蓝油烯 (1),得到产率高达 80% 的标题双愈创蓝油烯二酮 (12),在氮气下于 60 °C 加热时定量得到标题 1-薁酮 (13) 。在各种条件下研究了12和13的氧化,这些化合物被证明是1自氧化得到的大量复杂产物的非常重要的关键中间体。
