  摘要：

  1-Methyl-5-(3-azido-2,3-dideoxy-beta-D-erythro-pentofuranosyl)uracil (C-AZT), a C-nucleoside isostere of the potent anti-AIDS nucleoside 3'-azido-3'-deoxythymidine (AZT), was synthesized. 1-Methyl-2'-deoxy-5'-O-tritylpseudouridine (2a) was oxidized with CrO3/pyridine/Ac2O complex to 1-methyl-5-(5-O-trityl-beta-D-glycero-pentofuranos-3-ulosyl) uracil (12a), which was selectively reduced to 1-methyl-5-(5-O-trityl-beta-D-threo-pentofuranosyl)uracil (13a). Mesylation of 13a to 14a followed by nucleophilic displacement of the mesyloxy group with azide afforded 3'-azido-2',3'-dideoxy-5'-O-trityl-1-methylpseudoridine (15a), which was detritylated to C-AZT. In a similar manner, 1-methyl-5-(2-deoxy-2-fluoro-beta-D-arabinofuranosyl)uracil (C-FMAU, a potent antiherpetic nucleoside) was converted into the 3'-azido analogue (3'-azido-C-FMAU). Both C-AZT and 3'-azido-C-FMAU, however, did not exhibit any significant inhibitory activity against HIV in H9 cells.
