Two approaches based on the ring-closing metathesis reaction have been explored for the synthesis of the core structure of the marine natural products, the aurisides. The second approach, accomplished in a stereocontrolled manner, used both a Brown's allylation and an Evans' aldolisation, and finally a transannular ketalization to deliver a highly functionalized auriside analogue.
已经探索了两种基于闭环复分解反应的方法来合成海洋天然产物金苷的核心结构。第二种方法以立体控制的方式完成,使用布朗烯丙基化和埃文斯醛醇化,最后使用跨环缩酮化来提供高度功能化的金苷类似物。
