the appropriate heterocycles (silylated uracil, thymine, N4-benzoylcytosine, N4-benzoyl-5-fluorocytosine, 6-chloropurine, and 6-chloro-2-fluoropurine) in the presence of Lewis acid afforded a series of 2'-fluorinated L-nucleoside analogues (15-18, 23-26, 36-45). The newly synthesized compounds were evaluated for their antiviral activities against HIV-1 in human peripheral blood mononuclear (PBM) cells
采用直接缩合法合成了含2'-氟乙烯的L-核苷类似物,并对其体外抗HIV和HBV活性进行了评价。由1,2-O-异亚丙基-L-甘油醛经(R)-2-氟丁烯内酯中间体5分五个步骤制备关键中间体8,即我们目标化合物的糖部分。在路易斯酸存在下,将乙酸酯8与适当的杂环(甲硅烷基尿嘧啶,胸腺嘧啶,N4-苯甲酰基胞嘧啶,N4-苯甲酰基-5-氟胞嘧啶,6-氯嘌呤和6-氯-2-氟嘌呤)偶联,得到一系列2'-氟化的L-核苷类似物(15-18、23-26、36-45)。评价了新合成的化合物对人外周血单核(PBM)细胞中HIV-1和2.2.15细胞中HBV的抗病毒活性。胞嘧啶23,
