The first total synthesis of extracellular factor, âAvenolideâ, in Streptomyces avermitilis has been achieved using a convergent approach. The stereogenic centers in two key segments were installed using Sharpless epoxidation and dihydroxylation. This synthetic study allowed the determination of the absolute configuration of avenolide as 4S,10R, and yielded important information on its structureâactivity relationship.
已经成功实现了在链霉菌(Streptomyces avermitilis)中对细胞外因子“Avenolide”的首次总合成,采用了收敛法。这两个关键片段中的立体中心是通过Sharpless环氧化和二羟基化反应构建的。这项合成研究确定了Avenolide的绝对构型为4S,10R,并提供了关于其结构-活性关系的重要信息。
