A convergent synthesis of fluvirucinin B1 from acid ent-6a and nitrile ent-9, involving an organocopper coupling, a stereoselective allylation, a ring-closing metathesis reaction, and a stereoselective hydrogenation as the key steps, is reported. The starting building blocks have been prepared in a straightforward manner from a common phenylglycinol-derived lactam 1. An unprecedented regioselective
fluvirucinin B的汇集合成1从酸ENT -图6a和腈ENT - 9,涉及有机铜耦合,立体选择性烯丙基化,一个闭环复分解反应,和立体选择性氢化为关键步骤报道。起始结构单元已由常见的苯基甘醇衍生的内酰胺1以直接的方式制备。苯基甘氨醇衍生的仲胺的区域选择性前所未有氧化5为羧酸6已经研制成功。
