A short and efficient synthesis of a diterpenoid with a 1,2-seco-cladiellane carbon skeleton is described, starting from geraniol and carvone. One-step oxidative cyclization with a RuO2/NaIO4 system leads to two diastereomeric, bicyclic triols, which contain six stereogenic centers and will be helpful in the synthesis of eleutherobin. The stereochemical outcome of this cyclization has been determined
用1,2-二萜类化合物的简短和高效合成开环-cladiellane碳骨架被描述,从香叶醇和香芹酮开始。用RuO 2 / NaIO 4系统进行的一步氧化环化反应会生成两个非对映异构的双环三醇,其中包含六个立体异构中心,将有助于合成eleutherobin。该环化的立体化学结果已经通过X射线分析确定。
