| Abstract: | The first copper‐catalyzed intermolecular 5+2] homodimerization of hydroxy p‐quinone is presented, furnishing bicyclo3.2.1]octadienone core structures in typically good yields and excellent diastereoselectivities. Applying this synthetic approach enables a concise nine‐step total synthesis of (?)‐perezoperezone from commercially available 3,5‐dimethoxytoluene. |
