To show the synthetic utility of palladium/norbornene (Pd/NBE) cooperative catalysis, here we report concise syntheses of indenone-based natural products, pauciflorol F and acredinone A, which are enabled by direct annulation between aryl iodides and unsaturated carboxylic acid anhydrides. Compared to the previous indenone-preparation approaches, this method allows simple aryl iodides to be used as
为了展示钯/降冰片烯 (Pd/NBE) 协同催化的合成效用,我们在此报道了基于茚酮的天然产物、少花酚 F 和 acredinone A 的简明合成,这些产物是通过芳基碘化物和不饱和羧酸酐之间的直接成环来实现的。与以前的茚酮制备方法相比,该方法允许使用简单的芳基碘化物作为底物,并完全控制区域选择性。acredinone A 的全合成以两种不同的 Pd/NBE 催化的邻位酰化反应为特征,用于构建五取代的芳烃核心,包括开发新的邻位酰化/原硼酸化。
