Palladium-catalyzed cross-coupling reactions of tin and zinc nucleophiles with arylsulfonates of pyrimidine nucleosides have been achieved to give a wide range of 4-C-substituted pyrimidine nucleosides. This method also allows the construction of pyrimidine-pyrimidinone dinucleosides, containing the carbon skeleton of the (6-4) DNA photo lesion.
在钯催化下,锡和锌亲核物与嘧啶核苷的芳基磺酸盐发生了交叉偶联反应,生成了多种 4-C 取代的嘧啶核苷。这种方法还可以构建含有 (6-4) DNA 光变碳骨架的嘧啶-嘧啶酮二核苷。
