interest in the synthesis of purine derivatives due to the discovery of purine-derived ligands for a variety of nucleotide dependent enzymes. The majority of chemistry has focused on substitution of the purine core structure by alkylation at N9 and nucleophilic–aromatic substitution reactions at C2 and C6. Here we report the syntheses of aryl, N-aryl, O-aryl substituted purine libraries by the palladium-mediated
近年来,由于发现了嘌呤衍生的用于多种核苷酸依赖性酶的配体,因此在嘌呤衍生物的合成中引起了人们的兴趣。大多数化学方法都集中在通过N9处的烷基化以及C2和C6处的亲核-芳族取代反应来取代嘌呤核心结构。这里,我们报告的芳基,的合成Ñ -芳基,ø -芳基取代的嘌呤库通过在C2位硼酸,苯胺或苯酚的钯介导的偶联,和铜(II)介导的Ñ -arylation与硼酸N9位置。此处描述的化学物质极大地扩展了我们引入不同功能并创建新嘌呤支架的能力。
