in about 30% overall yield in 6 steps via key intermediates, protected 3′-deoxy-‘arabino’-nucleosides, which were obtained by deoxygenative [1,2]-hydride shift and β-elimination reactions of sulfonylated ribo-counterparts. Xanthine analogues (9X and 16X) were prepared from the corresponding guanine nucleosides. The unprotected 3′-deoxy-‘arabino’-nucleosides (9U,C,A,G,H,X) and their azido nucleosides
标题核苷(16U,Ç,G ^并ħ)从嘧啶和嘌呤核糖核苷在约30%的总收率在6个步骤合成经由关键中间体,被保护的3'-脱氧“阿拉伯”核苷,这是由deoxygenative [获得磺酰化核糖体的1,2,]-氢化物转移和β-消除反应。黄嘌呤类似物(9X和16X)是从相应的鸟嘌呤核苷制备的。未保护的3'-脱氧- '阿拉伯糖'-核苷(9U,C,A,G,H,X)及其叠氮核苷16对小鼠的HIV体外或P388白血病均未显示任何显着活性。
