A strategy of general applicability toward seco-prezizaane sesquiterpenes, from a chiral, tricyclic synthon, readily available via an enzymatic resolution step from the Diels–Alder adduct of cyclopentadiene and p-benzoquinone, has been devised. Our approach enables harnessing of the stereochemical proclivities of the norbornyl system to install the desired stereochemistry at the key stereogenic centers
朝向普遍适用性的策略开环经由从环戊二烯和的狄尔斯-阿尔德加合物的酶促拆分步骤-prezizaane倍半萜烯,从手性,三环合成子,容易获得p醌,已被设计出来。我们的方法能够利用降冰片基系统的立体化学倾向,在关键的立体成因中心安装所需的立体化学。采取有趣的策略将立体化学分歧重新调整为立体再收敛,这是我们成功方法的基石。已完成seco -prezizaane子类的典型成员(+)-1 S -minwanenone的第一个全合成。
