A concise chemical synthesis of (+)-haperforin G in 20 steps from commercially available starting materials is achieved with the integration of the Co-catalyzed intramolecular Pauson-Khand reaction for the stereoselective construction of cyclopentanone bearing an all-carbon quaternary stereogenic center at the bridge-head position and the light-initiated photocatalysis for convergent and asymmetric

(+)-Haperforin G was synthesized in 20 steps from commercially available starting materials. A Co-catalyzed intramolecular Pauson–Khand reaction was used for stereoselective construction of cyclopentanone bearing an all-carbon quaternary stereogenic center at the bridge-head position. Light-initiated photocatalysis was used for convergent and asymmetric cross-coupling of the unstabilized C(sp3) radical
(+)-Haperforin G 由市售起始原料经过 20 个步骤合成。共催化分子内 Pauson-Khand 反应用于立体选择性构建在桥头位置带有全碳四元立构中心的环戊酮。光引发的光催化用于不稳定的C(sp 3 )自由基与烯酮的会聚和不对称交叉偶联。所开发的化学方法为合成结构多样的 haperforin G 类似物铺平了道路 ( 6 )。
