  Design, synthesis and biological evaluation of 2′-deoxy-2′,2′-difluoro-5-halouridine phosphoramidate ProTides

  摘要：

  We report the synthesis of a series of novel 2'-deoxy-2',2'-difluoro-5-halouridines and their corresponding phosphoramidate ProTides. All compounds were evaluated for antiviral activity and for cellular toxicity. Interestingly, 2'-deoxy-2',2'-difluoro-5-iodo- and -5-bromo-uridines showed selective activity against feline herpes virus replication in cell culture due to a specific recognition (activation) by the virus-encoded thymidine kinase.

  An efficient two-step procedure for the syntheses of pyrimidine nucleosides is presented. A series of glycosyl 5-(aminomethylene)-1,3-dioxane-4,6-dione derivatives were prepared from β-anomeric isonitriles by reaction with Meldrum’s acid or by allowing aminomethylene Meldrum’s acid to react with an 1-aldofuranosyl halide or acetate. The resultant 5-(aminomethylene)-1,3-dioxane-4,6-dione derivatives

  提出了一种合成嘧啶核苷的有效两步法。一系列糖基 5-(氨基亚甲基)-1,3-二恶烷-4,6-二酮衍生物通过与 Meldrum 酸反应或通过使氨基亚甲基 Meldrum 酸与 1-醛糖呋喃基卤化物或乙酸盐反应，从 β-异头异腈制备. 生成的 5-(aminomethylene)-1,3-dioxane-4,6-dione 衍生物通过转酰基反应与异氰酸苄基或 2,4-二甲氧基苄基酯反应，得到 uridine-5-carboxylic acid 衍生物和相关核苷。这些核苷羧酸通过用N-溴代琥珀酰亚胺进行溴代脱羧而转化为其他 C-5 衍生物。
