The total synthesis of gravicycle, isolated from Grevillea robusta, has been achieved for the first time. The key step of our synthetic process is the efficient assembly of a highly functionalized biaryl ether via the copper-catalyzed O-arylation of suitably protected pyrogallol-5-carboxylate, using triarylbismuth(V) diacetate.
我们首次实现了从罗布麻属植物中分离出的葡萄酸的全合成。我们合成过程的关键步骤是利用二乙酸三芳基铋(V),通过铜催化适当保护的焦醛-5-羧酸酯的 O-芳基化反应,有效地组装出高度官能化的双芳基醚。
