  Practical Synthesis of 2‘-Deoxy-4‘-thioribonucleosides:  Substrates for the Synthesis of 4‘-ThioDNA

  摘要：

  [GRAPHIC]We report herein a practical synthesis of 4'-thiothymidine (15) and appropriately protected 2'-deoxy-4'-thiocytidine (16), -thioadenosine (27), and -thioguanosine (29) derivatives, substrates for the synthesis of 4'-thioDNA, from the corresponding 4'-thioribonucleosides. 2'-Deoxy-4'-thiopyrimidine nucleosides were synthesized using a radical reaction of the corresponding 2'-alpha-bromo derivatives, which were prepared via 2,2'-O-anhydro derivatives. 2'-Deoxy-4'-thiopurine nucleosides were synthesized using the same radical reaction of the corresponding 2'-beta-bromo derivatives.

  the synthesis of appropriately protected 2′-deoxy-2′-fluoro-4′-thiouridine (5), -thiocytidine (7), and -thioadenosine (35) derivatives, substrates for the synthesis of novel modified RNAs. The synthesis of 5 and 7 was achieved via the reaction of 2,2′-O-anhydro-4′-thiouridine (3) with HF/pyridine in a manner similar to that of its 4′-O-congener whereas the synthesis of 35 from 4′-thioadenosine derivatives

  我们在此报告了适当保护的2'-脱氧-2'-氟-4'-硫尿苷（5），-硫胞苷（7）和-硫代腺苷（35）衍生物（合成新型修饰RNA的底物）的合成。合成5和7经由2,2'-的反应实现ø -anhydro -4'-硫代尿苷（3）用HF /吡啶的方式类似于其4'-的ö -congener而合成来自4'-硫代腺苷衍生物的35个未成功。因此，35是通孔的糖基化合成氟化4- thiosugar 25与6-氯嘌呤。X射线晶体结构分析显示2'-脱氧-2'-氟-4'-硫代胞苷（8）主要采用与2'-脱氧-2'-氟胞苷相同的C3'-内构象。
