accomplished and their antiviral activity against orthopox viruses have been evaluated. The key intermediate, L-cyclopent-2-enone 13 was prepared from D-ribose using a ring closing metathesis reaction in eight steps. Among the synthesized nucleosides, the adenine 2 (Neplanocin A), cytosine 14, and 5-F-cytosine 15 analogues exhibited potent anti-orthopox virus activity, including smallpox virus.
一种用于合成对映体纯的 D-环戊烯基核苷的改进方法已经完成,并且已经评估了它们对正痘病毒的抗病毒活性。关键中间体 L-cyclopent-2-enone 13 由 D-核糖使用闭环复分解反应分八步制备而成。在合成的核苷中,腺嘌呤 2 (Neplanocin A)、胞嘧啶 14 和 5-F-胞嘧啶 15 类似物表现出有效的抗正痘病毒活性,包括天花病毒。
