synthesis of a large series of diverse 6-(N-substituted aminomethyl)-, 6-(O-substituted hydroxymethyl)- and 6-(S-substituted sulfanylmethyl)purine nucleosides (55 examples of both ribo- and 2'-deoxyribonucleosides), aimed at identifying novel homologues of natural nucleosides, was developed. The key transformation involved nucleophilic substitutions of Tol-protected 6-(mesyloxymethyl)purine nucleosides
高效,简便地合成大量不同的6-(N-取代的氨基甲基)-,6-(O-取代的羟甲基)-和6-(S-取代的硫烷基甲基)嘌呤核苷(55个核糖基和2个例子)开发了“-脱氧核糖核苷”,旨在鉴定天然核苷的新同源物。关键的转化涉及由伯或仲胺,醇盐或硫醇盐对Tol保护的6-(甲氧基甲氧甲基)嘌呤核苷进行亲核取代。尽管2'-脱氧核糖核苷是无活性的,但核糖核苷却发挥了相当大的细胞抑制作用,并具有一些低选择性的抗HCV活性。
