  摘要：

  Treatment of 2,2'-anhydro-1-beta-D-arabinofuranosyluracil with thiolate anions gave the 2'-S-alkyl(and aryl)-2'-thiouridines (1). Oxidation of 3',5'-di-O-acetyl-2'-S-alkyl(and aryl)-2'-thiouridines (2) with 3-chloroperoxybenzoic acid (MCPBA) gave the diastereomeric sulfoxides 4. Treatment of 2 with XeF2 or 4 with (diethylamino)sulfur trifluoride/SbCl3 gave the diastereomeric 3',5'-di-O-acetyl-2'-S-alkyl(and aryl)-2'-fluoro-2'-thiouridines (9). These alpha-fluoro thioethers were oxidized (MCPBA) to their stable sulfone derivatives 11 that are analogues of the biologically active 2'-deoxy-2',2'-difluoro nucleosides. Stereochemistry (2'S) and conformations of the major diastereomers were established by X-ray crystallography. Efficient conversions of 11 to the cytidine alpha-fluoro sulfones 14 were achieved.

  Studies directed toward the oxidative and reductive desulfurization of readily available 2'-S-aryl-2'-thiouridine derivatives were investigated with the prospect to functionalize the C2'-position of nucleosides. The oxidative desulfurization-difluorination strategy was successful on 2-(arylthio)alkanoate surrogates, while extension of the combination of oxidants and fluoride sources was not an efficient

  针对易于获得的2'-S-芳基-2'-硫代尿苷衍生物的氧化和还原脱硫的研究进行了研究，具有使核苷的C2'-位官能化的前景。氧化脱硫-二氟化策略在2-（芳硫基）链烷酸酯替代物上是成功的，而氧化剂和氟化物源组合的扩展当应用于2'-S-芳基-2'-硫代尿苷衍生物时不是有效的氟化方案，因此主要发生在嘧啶环的C5-卤代反应和C2'-单氟化而不脱硫的过程中。2'-芳基磺酰基-2'-脱氧尿苷及其2'-氟化类似物的循环伏安法显示，尽管在相对较高的阴极电位下，仍可能发生芳基砜部分的裂解。2'-芳基磺酰基-2'-脱氧尿苷与有机电子给体（OED）的还原-脱磺酰化主要产生碱诱导的呋喃类产物，而α-氟砜衍生物的化学（OED）和电化学还原-脱磺酰化产生2'-脱氧2'-氟尿苷和2'，3'-二氢-2'，3'-二脱氧2'-氟尿苷衍生物。这些结果提供了通过碳-硫键裂解产生C2'-阴离子的良好证据，为核苷中的还原功能化方法开辟了
