Highly functionalized C6-aryl-substituted purine analogues were synthesized through direct arylation of 6-chloropurine with aromatics promoted by anhydrous AlCl(3) in a single step. The reactions, which were conducted using a 3-fold excess of AlCl(3) in refluxing 1,2-dichloroethane, gave moderate to excellent product yields in 0.5 h. This work is complementary to the classical coupling reactions for the synthesis of C6-aryl-substituted purine analogues.
通过无水 AlCl(3) 促进的 6-氯嘌呤与芳烃的直接芳基化反应,一步法合成了高官能化的 C6-芳基取代嘌呤类似物。在回流的 1,2-二氯乙烷中使用 3 倍过量的 AlCl(3)进行反应,在 0.5 小时内可得到中等至优秀的产物收率。这项工作是对经典的 C6-芳基取代嘌呤类似物合成偶联反应的补充。
