The synthesis of the core unit of cycloaraneosene and ophiobolin M has been investigated, following a general strategy applicable to both 5-8 bicyclic systems. The synthetic strategy includes a ring-closing metathesis reaction to generate the central eight-membered ring as well as a palladium-mediated coupling of a Grignard reagent to introduce the exocyclic side-chain. The stereochemistry of the ring
按照适用于 5-8 双环系统的一般策略,已经研究了环芳烷烃和 ophiobolin M 的核心单元的合成。合成策略包括闭环复分解反应以产生中心八元环以及钯介导的格氏试剂偶联以引入环外侧链。还讨论了环结的立体化学,并实现了适度的非对映选择性。(C) Wiley-VCH Verlag GmbH,69451 德国魏因海姆,2002 年。
