Abstract A synthetic study toward the structurally complex rearranged-type C19-diterpenoid alkaloids leading to construction of the strained 6/3/5/6 tetracyclic core is presented. The synthesis features an intramolecular Diels–Alder cycloaddition reaction to assemble the highly substituted central cyclopropane motif, which may serve as a key strategy for the total synthesis of relevant natural product molecules
摘要提出了一种结构复杂的重排型C19-二萜生物碱的合成研究,该生物碱可导致构建应变的6/3/5/6四环核。该合成具有分子内Diels–Alder环加成反应,以组装高度取代的中心环丙烷基序,这可能是相关天然产物分子完全合成的关键策略。
