title: Synthesis and anti-HIV activity of C4-modified pyrimidine nucleosides.
abstract: One-pot syntheses provided a series of triazole- and pentafluorophenyloxy-substituted pyrimidine nucleosides. Most of the compounds in the series displayed anti-HIV activities but none as potent as AZT 2. 1-(beta-D-Erythro-pentofuranosyl)-4-pentafluorophenyloxy-2(1H)-pyr imidinone 14 was the most potent and the most selective compound in the series with EC50 = 1.6 microM.
