  Inspired by a new biosynthetic hypothesis, we report a biomimetic total synthesis of atrachinenins A and B that explains their racemic nature. The synthesis exploits an intermolecular Diels–Alder reaction between a quinone meroterpenoid and E-β-ocimene, followed by intramolecular (3 + 2) cycloaddition and a late-stage aerobic oxidation. Divergent transformations of a simple model system gave several

  受新的生物合成假设的启发，我们报告了 atrachinenins A 和 B 的仿生全合成，这解释了它们的外消旋性质。该合成利用了醌类萜类化合物和E -β-罗勒烯之间的分子间 Diels-Alder 反应，然后是分子内 (3 + 2) 环加成和后期有氧氧化。一个简单模型系统的发散转变给出了几个复杂的多环支架，同时也暗示了 atrachinenin C 的结构修正。
• 5-Lipoxygenase and Cyclooxygenase-1 Inhibitory Active Compounds from <i>Atractylodes lancea</i>
  作者：Marion Resch、Alois Steigel、Zhong-liang Chen、Rudolf Bauer

  DOI：10.1021/np970430b

  日期：1998.3.1

  Lipophilic extracts of Atractylodes lancea rhizomes exhibited potent inhibitory activities in 5-lipoxygenase [IC50 (5-LOX) = 2.9 mu g/mL (n-hexane extract)] and cyclooxygenase-1 [IC50 (COX-1) = 30.5 mu g/mL (n-hexane extract)] enzymatic assays. Bioactivity-guided fractionation of the n-hexane extract led to the isolation of a new compound atractylochromene (1), a potent inhibitor in both test systems [IC50 (5-LOX) = 0.6 mu M, IC50 (COX-1) = 3.3 mu M] Also obtained was 2-[(2E)-3,7-dimethyl-2,6-octadienyl]-6-methyl-2,5-cyclohexadiene-1,4-dione (2), which showed a selective inhibitory activity against 5-LOX [IC50 (5-LOX) 0.2 mu M, IC50 (COX-1) 64.3 mu M]. The sesquiterpene atractylon (3) and the coumarin osthol (4) turned out to be moderate but selective 5-lipoxygenase inhibitors. Atractylenolides I (5), II (6), and III (7) showed no significant inhibitory effects for either enzyme. Structures were established by spectral data interpretation.
