  Microwave promoted C6-alkylation of purines through SNAr-based reaction of 6-chloropurines with 3-alkyl-acetylacetone

  摘要：

  通过 6-氯嘌呤衍生物与 3-烷基-乙酰丙酮的 SNAr 反应，以良好至极佳的分离产率获得了 C6-烷基化嘌呤类似物。采用 3-烷基乙酰丙酮作为烷化剂，在微波辐照条件下，在很短的反应时间内高选择性地获得了 C6-烷基化嘌呤。这项工作是对合成 C6-烷基化嘌呤类似物的经典偶联反应的补充。

  synthesis of purines bearing functionalized carbon substituents or methyl in position 6 was developed. Under different reaction conditions, 6-halopurine derivatives could react with ethyl acetoacetate efficiently to yield 2-(purin-6-yl)acetoacetic acid ethyl esters, (purin-6-yl)acetates and 6-methylpurines respectively. No metal catalyst and ligand were required.

  C6-Alkylated purine analogues were obtained in good to excellent isolated yields by SNAr reaction of 6-chloropurine derivatives with 3-alkyl-acetylacetone. 3-Alkyl-acetylacetones were employed as alkylating agents and C6-alkylated purines were obtained highly selectively within short reaction time under microwave irradiation conditions. This work is complementary to the classical coupling reactions for the synthesis of C6-alkylated purine analogues.
