The marine natural product cyclodidemniserinol trisulfate displayed moderate HIV-1 integrase inhibitory activity. Its novel structure triggered our interest to synthesize it. In our total synthesis effort, the natural product was dissected into four fragments based on the rational retrosynthetic analysis. All four fragments were successfully prepared with orthogonal protection. And the assembly of
海洋天然产物环硫酸二环亚氨基三醇显示出中等的HIV-1整合酶抑制活性。它的新颖结构激发了我们对其进行合成的兴趣。在我们的总合成努力中,基于合理的逆向合成分析,将天然产物分为四个片段。用正交保护成功制备了所有四个片段。在NaHCO 3存在下,通过I 2介导的脱保护和分子内缩酮形成串联反应,片段A和片段B的装配提供了C 5 –C 30关键亚基。在MeCN中。我们的工作提供了灵活实用的方法来合成和衍生基于3,5,7-三取代的6,8-二氧杂双环[3.2.1]辛烷的类似物,以寻找新的结构HIV-1整合酶抑制剂。
