The synthesis of 5-heteroaryl-substituted 2'-deoxyuridines is described. The heteroaromatics were obtained from three different 5-substituted 2'-deoxyuridines. Cycloaddition reaction of nitrile oxides on the 5-ethynyl derivative 1 gave the isoxazoles 4a-e. The thiazole derivatives 14a-c were obtained from the 5-thiocarboxamide 11, while 5-pyrrol-1-yl-2'-deoxyuridine (17) could be synthesized directly
描述了5-杂芳基取代的2'-脱氧尿苷的合成。杂芳族化合物获自三种不同的5-取代的2'-脱氧尿苷。腈氧化物在5-乙炔基衍生物1上的环加成反应得到异恶唑4a-e。噻唑衍生物14a-c从5-硫代羧酰胺11获得,而5-吡咯-1-基-2'-脱氧尿苷(17)可以直接从5-氨基-2'-脱氧尿苷合成。评价化合物的抗病毒活性。注意到针对5-(3-溴异x唑-5-基)-2'-脱氧尿苷(4c)的针对1型单纯疱疹病毒(HSV-1)和水痘带状疱疹病毒(VZV)的选择性活性。该化合物对单纯疱疹病毒2型,巨细胞病毒和缺乏胸腺嘧啶激酶(TK)的HSV-1和VZV突变体无活性,这表明最有可能的是,
