  Synthesis and Anti-HIV Activity of 4′-Substituted 4′-Thiothymidines: A New Entry Based on Nucleophilic Substitution of the 4′-Acetoxy Group

  摘要：

  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).
