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. (C) 2013 De-Sheng Mei, Wen-Hu Duan.
