nosylpurine nucleosides was prepared and evaluated for cytotoxicity. The details of a convenient synthesis of the carbohydrate precursor 4-C-hydroxymethyl-3,5-di-O-benzoyl-2-fluoro-alpha-D-arabinofuranosyl bromide (13) are presented. Proof of the structure and configuration at all chiral centers of the sugars and the nucleosides were obtained by proton NMR. All five target nucleosides were evaluated
制备一系列4'-C-羟甲基-2'-氟-D-阿拉伯呋喃糖基嘌呤核苷,并评价其细胞毒性。给出了碳水化合物前体4-C-羟甲基-3,5-二-O-苯甲酰基-2-氟-α-D-阿拉伯呋喃糖基溴化物(13)的方便合成的细节。通过质子NMR获得糖和核苷的所有手性中心的结构和构型的证明。评价了全部五个靶核苷在人肿瘤细胞系中的细胞毒性。4'-C-羟甲基氯法拉滨类似物(16beta)在CCRF-CEM白血病细胞中显示出轻微的细胞毒性。
