Asymmetric entry to the bicyclic core structure of (+)-hyperforin is presented. The developed synthetic strategy features a carefully orchestrated stereochemical relay from the single chiral center residing within (–)-Wieland–Miescher ketone and an intramolecular aldol reaction to cast the [3.3.1] bicyclic scaffold found in a diverse array of polycyclic polyprenylated acylphloroglucinols.
不对称进入 (+)-hyperforin 的双环核心结构。所开发的合成策略具有精心编排的立体化学中继,来自驻留在 (-)-Wieland-Miescher 酮内的单个手性中心和分子内醛醇反应,以铸造在各种多环聚异戊二烯化酰基间苯三酚中发现的 [3.3.1] 双环支架。
