Phelligridin G is an unusual natural product that contains an embedded spiro-fused furanone core. We have investigated two furan-based synthetic approaches towards the spirocyclic core structure of this natural product from readily available 2-phenylfurans. Although initial studies involving an oxidative cyclization were unsuccessful, we were ultimately able to access this key system through a sequential
Phelligridin G 是一种不寻常的天然产品,含有嵌入的螺融合呋喃酮核。我们已经从现成的 2-苯基呋喃中研究了两种基于呋喃的合成方法,以研究这种天然产物的螺环核心结构。尽管涉及氧化环化的初步研究未成功,但我们最终能够通过连续的分子间呋喃 Diels-Alder 反应和基于复分解的重组来访问这个关键系统。一种相关的方法导致扩展的 C 环形成螺稠合的吡喃螺环。
