A phloroglucinol‐terpene adduct (PTA) collection consisting of twenty‐four molecules featuring three skeletons was discovered from Baeckea frutescens. Inspired by its biosynthetic hypothesis, we synthesized this PTA collection by reductive activation of stable phloroglucinol precursors into highly reactive ortho‐quinone methide (o‐QM) intermediates and subsequently Diels–Alder cycloaddition.

从苦菜(Baeckea frutescens)中发现了由24个具有三个骨架的分子组成的
间苯三酚-萜烯加合物(
PTA)集合。受其
生物合成假说的启发,我们通过将稳定的
间苯三酚前体还原活化为高反应性邻醌甲基化(o- QM)中间体,然后进行Diels-Alder环加成反应,合成了
PTA集合。我们还通过进行动态NMR和HPLC-MS监测实验首次证明了活性o- QM的生成过程。此外,
PTA收集物对小菜蛾幼虫具有显着的拒食作用。
