A concise total synthesis of spirocurcasone was accomplished. Key features of the synthesis involved a vinylogous Mukaiyama aldol reaction, a Carroll rearrangement of β-keto allyl ester derivative, an intramolecular aldol condensation, and a spiro ring formation by ring-closingmetathesis of the pentaene compound. This synthetic work was complete in nine steps from (S)- or (R)-perillaldehyde without
