A concise asymmetric synthesis of (-)-halenaquinone is described. The synthesis features a diastereoselective Heck cyclization to set a quaternary center as well as a novel intramolecular inverse-electron-demand Diels-Alderreaction involving a vinylquinone. The synthesis is highly convergent and features a minimal amount of protecting group manipulations.
