Abstract
(±)-Deoxyquinone A dimethyl ether (1) has been synthesized from 5,7-dimethoxy-1-naphthol. This is the first synthesis of an aphin-derived pyranonaphthoquinone, the (+)-enantiomer having been obtained from natural sources. The (±)-cis epimer (3),7-methoxyeleutherin, a plant product, was also obtained for the first time.Keywords
