A total synthesis of brevenal is described. The pentacyclic ether core was constructed by the intramolecular allylation of α-acetoxy ether and subsequent ring - closing metathesis. Both of the diene side chains were introduced by Wittig olefination and a Horner - Wadsworth - Emmons reaction, respectively, in a highly stereoselective manner.
