The syntheses of four pyrimidine C-nucleosides are described. These derivatives are designed as mimics of dC and dU, and in that respect, each can form two hydrogen bonds with complementary dG or dA residues. The minor groove O2 carbonyl in each derivative is replaced by a fluorine or a methyl group. The key carbon−carbon bond connecting the heterocycle to the carbohydrate is formed using a Heck-type
描述了四个嘧啶C-核苷的合成。这些衍生物被设计为dC和dU的模拟物,在这方面,每个衍生物均可与互补的dG或dA残基形成两个氢键。每个衍生物中的小沟O 2羰基被氟或甲基取代。使用Heck型钯介导的偶联反应可形成将杂环与碳水化合物连接的关键碳-碳键。
