efficient synthetic route to novel 2′,2′-difluoro 5′-norcarbocyclic phosphonic acid nucleosides from but-3-en-1-ol 5 is described. The discovery of 2′-fluorinated furanose nucleoside 1 as a potent anti-HIV-1 agent has led to the synthesis and biological evaluation of 2′-modified 5′-norversions of the carbocyclic phosphonate nucleosides. The synthesized nucleoside analogues 18, 19, 23a, 23b, and 24 were
描述了从but-3-en-1-ol 5到新的2',2'-二氟5'-降碳环膦酸核苷的非常有效的合成途径。作为有效的抗HIV-1剂的2'氟化呋喃糖核苷1的发现导致了碳环膦酸酯核苷2'修饰的5'-反型的合成和生物学评估。将合成的核苷类似物18,19,23A,23B,和24分别为抗HIV活性以及细胞毒性测试。腺嘌呤类似物19显示出显着的抗HIV-1活性(EC 50 = 13μM)。
