although of potential RNA antiviral interest, are virtually unknown. This paper reports on approaches to the synthesis of base-modified hypoxanthine 3'-deoxynucleosides. All of the target compounds are new and contain functionality at the 2-position that can be further elaborated for the synthesis of a variety of other novel analogues of 3'-deoxyinosine. Intact natural guanosine was used as the precursor
3'-脱氧肌苷的类似物尽管具有潜在的RNA抗病毒作用,但实际上是未知的。本文报道了合成碱基修饰的次黄嘌呤3'-脱氧核苷的方法。所有的目标化合物都是新的,并且在2位上含有官能团,可以进一步详述这些官能团以合成3'-脱氧肌苷的各种其他新颖类似物。完整的天然鸟苷用作前体,利用的关键转化是区域选择性双甲硅烷基化热自由基脱氧,区域特异性自由基卤化,金属介导的官能化和选择性臭氧分解。所描述的合成方法在进入3'-脱氧肌苷的新类似物方面具有相当大的普遍性。fa] 1。
