total synthesis of (±)-furanether A, which exhibits good antifeedant activity, has been concisely achieved in 13 linear steps. Notably, the key rigid tetracyclic skeleton containing a 1-methyl-8-oxabicyclo[3.2.1]octane moiety with two vicinal quaternary carbon centers was rapidly constructed in one step through a unique tandem C–H oxidation/oxa-[3,3] Cope rearrangement/aldol cyclization sequence.
(±)-呋喃醚 A 的首次全合成,具有良好的拒食活性,通过 13 个线性步骤简明地实现。值得注意的是,通过独特的串联 C-H 氧化/oxa-[3,3 ] 应对重排/醛醇环化序列。
