Salvilenone 1, a phenalenone diterpene isolated from the roots of Salvia miltiorrhiza Bunge, was synthesized in thirteen steps from resorcinol dimethyl ether. Dihydrophenalenol derivative 19, a key intermediate, was treated with aqueous hydrobromic acid to give salvilenone accompanied by the formation of a hydroxy diketone 20.
