The potent antiviral potential of 5'-amino-5'-deoxy-5'-noraristeromycin (2) is limited by associated toxicity. To seek derivatives of 2 that circumvent this undesirable property, three amino substituted derivatives (acetyl, 3; formyl, 4; and methyl, 5) of 2 have been prepared in 4-7 steps from the same intermediate, (1S,4R)-4-(6-chloropurin-9-yl)cyclopent-2-en-1-ol (6). Key steps involved an improved
5'-氨基-5'-脱氧-5'-去甲诺霉素(2)的强大抗病毒潜力受到相关毒性的限制。为了寻找2的衍生物来避免这种不希望的特性,已经从同一中间体(1S,4R)-的4-7个步骤制备了3个2的氨基取代衍生物(乙酰基,3;甲酰基,4;和甲基,5)- 4-(6-氯嘌呤-9-基)环戊-2-烯-1-醇(6)。关键步骤涉及改进的Pd(0)催化的烯丙基叠氮化和新型Pd(0)催化的烯丙基酰胺化。对这三种目标化合物进行了抗大量病毒的评估,发现它们没有活性,只是5对人巨细胞病毒,水痘带状疱疹病毒和爱泼斯坦-巴尔病毒的作用非常弱。新衍生物也没有明显的细胞毒性。因此,
