three lactone units, and nine consecutive stereocenters, (−)-cephalotanin B is a structurally unusual member of the Cephalotaxus diterpenoids, natural products with intriguing molecular frameworks and promising biological properties. An enantioselective route to (−)-cephalotanin B is reported that is also applicable to (+)-cephalotanin B.
(−)-三尖杉宁 B 具有极其拥挤的七环骨架、三个内酯单元和九个连续的立构中心,是三尖杉属二萜类化合物中结构上不寻常的成员,是具有有趣的分子框架和有前景的生物特性的天然产物。据报道,(−)-头孢菌素 B 的对映选择性途径也适用于 (+)-头孢菌素 B。
