  Selective alkylation of pyrimidyl dianions II: synthesis, characterization, and comparative reactivity of 3′, 5′-o-bis- tetrahydropyranyl, trimethylsilyl and tert-butyldimethylsilyl derivatives of 5-bromo-2′-deoxyuridine

  摘要：

  Three compounds which can be used as precursors for thymidine synthesis via methylation at the 5 position, including 3', 5'-o-bis(tetrahydropyranyl)-5-bromo-2'-deoxyuridine 1a, 3', 5'-o-bis-(trimethylsily)-5-bromo-2'-deoxyuridine 1b, and 3', 5'-o-bis-(t-butyldimethylsilyl)-5-bromo-2'-deoxyuridine 1c, were prepared isolated and characterized by spectroscopic methods. Alkylation with methyl iodide using an organo-lithium reagent at low temperature produced 72%, 41% and 74% of thymidine 6, respectively. Tetrahydropyranyl and t-butyldimethylsilyl ethers are found to be better precursors for introduction of a methyl group at the 5 position.

  5-Substituted-4-thio-2'-deoxyuridine nucleosides have been chemically synthesized and studied by NMR and UV spectroscopy. The results have been analyzed and discussed in connection with the previous data. The imino proton signal and the carbon signal of the thiocarbonyl group in the 5-substituted-4-thio-2'-deoxyuridines were found to be at much lower field, offering a potential for monitoring these

  5-Substituted-4-thio-2'-deoxyuridine nucleosides 已被化学合成并通过 NMR 和 UV 光谱进行了研究。已经结合先前的数据对结果进行了分析和讨论。发现 5-取代-4-硫代-2'-脱氧尿苷中的亚氨基质子信号和硫代羰基的碳信号处于低得多的场中，为在 DNA 水平上监测这些修饰碱基提供了潜力。所有 4-硫代核苷在 340 nm 附近都有很强的吸收，因此可用作潜在的 UVA 诱导的抗癌剂。
