From termite soldier's secretions: The enantioselective total synthesis of the diterpene (+)‐cubitene is described. The route is characterized by the cyclization of a carvone‐derived C20 allylphosphate with SmI2, followed by fragmentation to the twelve‐membered ring. As a result, perfect stereocontrol of the isopropenyl‐substituted positions is achieved.
根据白蚁士兵的分泌物:描述了二萜(+)-肘烯的对映选择性全合成。该路线的特征是将香芹酮衍生的C 20烯丙基磷酸与SmI 2环化,然后断裂成十二元环。结果,实现了对异丙烯基取代位置的完美立体控制。
