Naphthotectone is a quinone isolated recently from teak extracts of Tectona grandis. It has been shown to be one of the most abundant compounds and the most active compound isolated form teak. Thus, it has been proposed that naphthotectone is one of the compounds responsible for the allelophathic activity of this plant. An efficient total synthesis of (±)-naphthotectone was achieved in seven steps
Naphthotectone 是一种最近从 Tectona grandis 柚木提取物中分离出来的醌。它已被证明是最丰富的化合物之一,也是从柚木中分离出来的最活跃的化合物。因此,有人提出萘烷是负责该植物化感作用的化合物之一。(±)-naphthotectone 的高效全合成通过七个步骤实现,总产率为 31%。通过使用含水 Wittig 反应作为关键步骤获得了最佳结果。使用的其他反应是通过 Corey-Chaykovsky 方法形成环氧化物环,以及创新的一锅阳极电氧化和去甲基化。
