A methodology for the syntheses of pyrimidine (C or U) 2-deoxyribonucleosides bearing bipyridine or terpyridine ligands attached via acetylene or phenylene linkers was developed based on single step cross-coupling reactions of unprotected 5-iodopyrimidine nucleosides with bipyridine or terpyridine acetylenes of phenyl boronates. The Sonogashira reactions with acetylenes were performed in DMF, while
基于未保护的5-碘嘧啶核苷与苯基硼酸酯的联吡啶或叔吡啶乙炔的单步交叉偶联反应,开发了一种方法,用于合成通过乙炔或亚苯基接头连接的带有联吡啶或三联吡啶配体的嘧啶(C或U)2-脱氧核糖核苷。与乙炔的Sonogashira反应在DMF中进行,而Suzuki与硼酸盐在水-乙腈混合物中的反应。研究了标题修饰核苷的光物理性质,以及(2,2'-联吡啶-5-基)乙炔基或(2,2'-联吡啶-5-基)苯基衍生物在> 300 nm处有吸收,在421处有亮发射选择-451 nm作为发光DNA标记的最佳候选者。 核苷-嘧啶-联吡啶-N-配体-交叉偶联反应
