  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.

  Diacetoxylation of 1-(2,5-dideoxy-beta-L-glycero-pent-4-eno-4-thiofuranosyl)thymine (13) with Pb(OAc)(4) allowed introduction of an acetoxy leaving group to the 4 '-position. Nucleophilic substitution of the resulting 4 '-acetoxy derivative (14) with silicon reagents enabled us to prepare the 4 '-phenylthio (17a), 4 '-azido (18a), 4 '-methoxy (20a), and 4 '-allyl (21a) analogues of 4 '-thiothymidine. 4 '-Cyano (25a) and 4 '-ethynyl (31) nucleosides were also synthesized from 3 ',5 '-bis-O-TBDMS derivative (24). Among novel 4 '-substituted 4 '-thiothymidines, the 4 '-azido (33), 4 '-cyano (36), and 4 '-ethynyl (37) derivatives were found to show potent inhibitory activity against HIV-1 and HIV-2. It is noteworthy that 36 and 37 were also inhibitory against replication of HIV variant resistant to 3TC (HIV-1(M184V)), being as potent as against HIV-1(IIIB).
