A novel synthesis of enantiopure N-Boc-norpandamarilactonine-A was established by employing a double ring-closing metathesis of a tetraene derivative, as a key step, where two five-membered rings were constructed in one step. N-Boc-Norpandamarilactonine-A was also converted to ent-norpandamarilactonine-A, and subsequently to pandamarilactonine-A and B.
通过采用四烯衍
生物的双闭环复分解反应作为关键步骤,建立了对映纯N -Boc-norpandamarilactonine- A的新型合成方法,其中一步构建了两个五元环。N -Boc-Norpandamarilactonine-A也被转化为ent -norpandamarilactonine-A,随后又被转化为pandamarilactonine-A和B。
