Amino imidazole carbonitrile derivatives decorated with α-amino acid side-chains have been synthesized by a multicomponent microwave assisted reaction inspired by the prebiotic chemistry of aminomalononitrile as a tool for generating high chemical diversity. These compounds were used as annulation synthons for the preparation of 8,9-disubstituted-6,9-dihydro-1-purin-6-ones by reaction with formic acid as a simple C-1 donor reagent. The novel heterocycles were characterized by significant activity against influenza A virus, amino imidazole carbonitrile derivatives showing the highest activity. Thus, the chemical complexity generated by prebiotic chemistry furnished a general tool for the identification of novel antiviral agents.
通过多组分微波辅助反应合成了带有α-氨基酸侧链的氨基咪唑腈衍生物,该反应受氨基丙二腈的益生元化学启发,作为产生高化学多样性的工具。这些化合物用作环化合成子,通过与作为简单C-1供体试剂的甲酸反应制备8,9-二取代-6,9-二氢-1-嘌呤-6-酮。这些新型杂环化合物对甲型流感病毒具有显著活性,氨基咪唑腈衍生物表现出最高活性。因此,益生元化学产生的化学复杂性为新型抗病毒药物的鉴定提供了一种通用工具。
