The natural product,1,7-dimethoxy-2-hydroxyxanthone(1),isolated from Securidaca inappendiculate Hassk,has a potential in the treatment of erectile dysfunction due to its significant relaxation activity on rabbit Corpus cavernosum.However,the isolation of compound 1 is problematic because of its high similarity in structure to its analogs.In this paper,the first synthesis of 1 was reported featuring two key reactions:a copper-catalyzed coupling reaction and an intramolecular cyclization.
