The acyl endoperoxide arteannuin H, recently reported as a novel natural product from Artemtsia annua, has been obtained in two steps from the photooxidation of dihydroartemisinic acid, thereby confirming biogenetic speculation regarding its derivation from a secondary allylic hydroperoxide. The little studied 3,2-rearrangement reaction of such allylic hydroperoxides is also discussed.
酰基内过氧化物青蒿素H,是最近报道的来自青蒿的一种新型天然产物,是从二氢青蒿酸的光氧化过程中分两个步骤制得的,从而证实了有关其衍生自仲烯丙基氢过氧化物的生物遗传学推测。还讨论了这种烯丙基氢过氧化物很少研究的3,2-重排反应。
