  The Suzuki-Miyaura cross-coupling reactions of 9-benzyl-6-chloropurine, 9- or 3-benzyl-8-bromoadenine and 2,6-dihalopurines with boronic acids gave the corresponding 6-, 8- or 2-aryl- or -alkenylpurines in good yields. Anhydrous conditions in toluene were superior for coupling of electron-rich boronic acids, while aqueous DME was used for electron-poor arylboronic acids as well as for alkenylboronic acids. A good regioselectivity was observed for the coupling of 2,6-dihalopurines: 9-benzyl-2,6-dichloropurine reacted with one equivalent of phenyl boronic acid to give 9-benzyl-2-chloro-6-phenylpurine, while an analogous reaction of 9-benzyl-6-chloro-2-iodopurine gave selectively 9-benzyl-6-chloro-2-phenylpurine.

  9-苄基-6-氯嘌呤、9-或3-苄基-8-溴腺嘌呤及2,6-二卤嘌呤与硼酸进行的铃木-宫浦交叉偶联反应，以良好产率得到了相应的6-、8-或2-芳基或烯基嘌呤衍生物。无水条件下以甲苯为溶剂对于富电子硼酸的偶联反应较为有利，而贫电子芳基硼酸及烯基硼酸则以含水的二甲氧基乙烷(DME)为溶剂进行反应。在2,6-二卤嘌呤的偶联反应中可以观察到良好的区域选择性：9-苄基-2,6-二氯嘌呤与一当量苯硼酸反应得到了9-苄基-2-氯-6-苯基嘌呤，而9-苄基-6-氯-2-碘嘌呤的类似反应则高选择性地得到了9-苄基-6-氯-2-苯基嘌呤。

  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.

  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。
