Novel arabinofuranosyl nucleosides and nucleotides having 2'-azido,2'-amino, or 2'-hydrocarbylamino substituents, which have antitumor, antiviral, and antimicrobial properties, are prepared by condensation of a pyrimidine, purine, or 1,3-oxazine base with an acylated 2-azido-2-deoxyarabinofuranosyl halide, followed by deblocking and catalytic hydrogenation, where appropriate, to convert the 2'-azido group to a 2'-amino group and, if desired, alkylation or the like to convert the 2'-amino group to a 2'-hydrocarbylamino group.
新型的具有2'-azido,2'-amino或2'-hydrocarbylamino取代基的
阿拉伯糖核苷和核苷酸,具有抗肿瘤、抗病毒和抗微
生物特性,通过将
嘧啶、
嘌呤或1,3-
噁唑碱基与酰化的2-azido-2-deoxyarabinofuranosyl卤代物缩合,然后进行去保护和催化氢化(如有必要),将2'-azido基转化为2'-amino基,并通过烷基化等方法将2'-amino基转化为2'-hydrocarbylamino基来制备。
