into the discovery of new anticancer drugs , we were interested in the preparation of naphthoquinone scaffolds bearing aminoalkyl side-chains. Following this aim, we revisited the Kochi–Anderson radical decarboxylation of amino acids in order to set up a versatile route to the direct functionalization of naphthoquinones. The best reaction conditions were applied to a selected series of compounds in a systematic
在我们正在进行的新抗癌药物发现研究计划中,我们对制备带有氨基烷基侧链的萘醌支架感兴趣。遵循这一目标,我们重新审视了氨基酸的 Kochi-Anderson 自由基脱羧反应,以建立一条通用途径来直接对萘醌进行功能化。在系统方法学研究中,将最佳反应条件应用于选定的一系列化合物,这使我们能够确定反应性的重要趋势。我们发现α-取代的β-氨基酸是最适合自由基加成的底物。相比之下,α-氨基酸给出了适度的结果。还研究了胺保护基团对反应结果的影响。这个实用的程序允许引入各种不对称部分,
