The first total synthesis of (+/-)-furanether A, which demonstrates good antifeedant activity, was achieved in 13 linear steps. 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.
