(+)-chamuvarinin, isolated from the root extract of Uvaria Chamae, utilizes a convergent modular strategy to construct the adjacently linked C15−C28 ether array, followed by a late-stage Julia−Kocienski olefination to append the butenolide motif. This constitutes the first total synthesis of (+)-chamuvarinin, defining the relative and absolute configuration of this unique annonaceous acetogenin.
(+)-chamuvarinin 的立体控制全合成,从Uvaria Chamae 的根提取物中分离,利用收敛模块化策略构建相邻连接的 C15-C28 醚阵列,然后是后期 Julia-Kocienski 烯化以附加丁烯内酯主题。这构成了 (+)-chamuvarinin 的首次全合成,定义了这种独特的番荔枝素的相对和绝对构型。
