The first total synthesis of the sesquiterpene (-)-cucumin H, a linear triquinane isolated from Macrocystidia cucumis, has been accomplished starting from (R)-limonene employing two different cyclopentannulation methodologies, which in addition to confirming the structure also established the absolute configuration of the natural product.

从(R)-柠檬烯开始,采用两种不同的环戊环法从倍半萜烯(-)-姜黄素H(一种从黄瓜大孢囊中分离出来的线性三喹烷)进行了第一个全合成,除了确认结构还建立了绝对构型天然产物。[反应:看文字]
