A series of 4-(1-alkynyl)-2(1H)-pyrimidinone ribonucleosides were synthesized from the Pd-catalyzed coupling of terminal alkynes to the 4-chloropyrimidin-2-one ribonucleoside (2). These compounds were hydrated, using three different methods, to afford the 4-(2-oxoalkylidene)-2(1H)-pyrimidinones. The 4-enol-pyrimidin-2-one structure of the title compounds offers functional groups with the potential
从末端炔与4-氯嘧啶-2-一核糖核苷的钯催化偶合中合成了一系列4-(1-炔基)-2(1 H)-嘧啶酮核糖核苷(2)。使用三种不同方法将这些化合物水合,得到4-(2-氧代亚烷基)-2(1H)-嘧啶酮。标题化合物的4-烯醇-嘧啶-2-酮结构提供具有沃森-克里克氢键潜力的官能团。
