The syntheses of members of a family of lindenane sesquiterpenoid [4+2] dimers led to the total syntheses of sarcandrolide J and shizukaol D. Inspired by a modified biosynthetic pathway, a cascade featuring furan formation/alkene isomerization/Diels–Alder cycloaddition was devised to construct the congested polycyclic architecture of the target molecules with the correct stereochemistry.

茚满倍半萜类 [4+2] 二聚体家族成员的合成导致了 sarcandrolide J 和 Shizukaol D 的全合成。 受改良的生物合成途径的启发,设计了以呋喃形成/烯烃异构化/Diels-Alder 环加成为特征的级联反应以正确的立体化学构建目标分子的拥塞多环结构。这项研究为这一天然产物家族开辟了开创性的合成入口,并为充分探索其生物学功能铺平了道路。
