1- and 9-(5-azido-2,3,5-trideoxy-beta-D-glycero-pent-2-enofuranosyl) derivatives (3a and 3b) of cytosine and adenine, respectively, has been accomplished via treatment of the corresponding 2',3'-unsaturated nucleosides (1a and 1b) with triphenylphosphine and carbon tetrabromide in the presence of lithium azide. Members of a new type of (aminoacyl)amino nucleoside, the 1- and 9-[5-(aminoacyl)amino-2
已完成分别合成胞嘧啶和腺嘌呤的1和9-(5-叠氮基2,3,5-三苯氧基-β-D-甘油-戊-2-烯呋喃糖基)衍生物(3a和3b)的直接合成。在叠氮化锂存在下,用三苯基膦和四溴化碳处理相应的2',3'-不饱和核苷(1a和1b)。新型(氨基酰基)氨基核苷的成员,胞嘧啶的1-和9- [5-(氨基酰基)氨基-2,3,5-三苯氧基-β-D-甘油-戊-2-烯呋喃糖基]衍生物通过将相应的不饱和氨基核苷与几种氨基酸衍生物的活性酯缩合,然后脱保护,分别获得腺嘌呤。检查了这些核苷在小鼠中对白血病L-1210和肉瘤180(实体瘤)的体内抗肿瘤活性;
