  Synthesis of 1,7-dimethoxy-2-hydroxyxanthone, a natural product with potential activity on erectile dysfunction

  摘要：

  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.

  Revision of the Structure of Fagaridine Based on the Comparison of UV and NMR Data of Synthetic Compounds

  摘要：

  Fagaridine is a quaternary benzo[c]phenanthridine alkaloid, originally isolated from Fagara xanthoxyloides in 1973. The assigned structure of this alkaloid was 7-hydroxy-8-methoxy-5-methyl-2,3-(methylenedioxy)-benzo[c]phenanthridinium (1). We have synthesized this compound, coded NK109, aiming at a practical antitumor drug, and during synthetic studies we questioned the original assigned structure. Thus, we synthesized 8-hydroxy-7-methoxy-5-methyl-2,3-(methylenedioxy)benzo[c]phenanthridinium (2), isomer of the assigned structure, and compared the spectroscopic data of both 1 and 2. The NMR data of 1 and 2 were very similar, but the UV spectra were completely different. The UV data for fagaridine agreed with these for 2; consequently, the true structure of fagaridine is 2, not 1.
