DOIAbstract
The total syntheses of rubiginone A<sub>2</sub>, C<sub>2</sub> and fujianmycin A are described. The synthesis involves Diels–Alder/aromatization and photo chemical reactions as key steps to construct the tetracyclic frame of benz[a]anthraquinone skeleton. Sharpless epoxidation, a copper-catalyzed regioselective epoxide opening, and enyne metathesis reactions are utilized as the key steps for the synthesis of chiral vinylcyclohexene
