The synthesis of 2′-β-C-methyl-neplanocin derivatives is described. The key intermediate cyclopentenyl alcohol 12 is prepared from sugar 5 in 12 steps. Coupling of 12 with appropriately protected purine, 7-deaza pyrimidine, uracil and pyrimidine bases via the Mitsunobu reaction followed by deprotection afforded the target cyclopentenyl nucleosides (18–23, 27). The synthesized compounds were evaluated
描述了2'-β- C-甲基-neplanocin衍生物的合成。关键中间体环戊烯基醇12由糖5以12个步骤制备。的耦合12与适当保护的嘌呤,通过Mitsunobu反应7-脱氮嘧啶,尿嘧啶和嘧啶碱基,接着脱保护得到目标环戊烯基核苷(18 - 23,27)。合成的化合物被评估为体外丙型肝炎病毒(HCV)的潜在抑制剂。不幸的是,它们都没有显示出低于EC 50 100μM的抗HCV活性。
