total syntheses of selaginpulvilins C and D is described. The key strategy for the construction of the core fluorene moiety involves in situ formation of an aryne intermediate followed by its formal hydrogenation. The precursor tetraynes that undergo aromatization via hexadehydro Diels–Alder reaction were prepared from readily available building blocks through typical alkyne-coupling reactions.
描述了Selaginpulvilins C和D的总合成。构建核心芴部分的关键策略涉及原位形成芳烃中间体,然后对其进行正式加氢。通过六氢Diels-Alder反应进行芳构化的前体四炔是通过典型的炔烃偶联反应从容易获得的结构单元中制备的。
