  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.

  perform direct β-selective glycosylation reactions with 2-deoxy-1,4-dithio-D-erythro-pentofuranosides has long been a significant stumbling block for the multi-gram synthesis of 4’-thio-2’-deoxy nucleosides. In addition, previously reported methods for the preparation of appropriately substituted 2-deoxy-1,4-dithio-D-erythro-pentofuranosides have proven problematic for large scale synthesis. To address
