cytosine derivatives were frequently accompanied by small amounts of the corresponding N,N-dimethylcytosine derivatives, which could be removed by ion-exchange chromatography. Carbodine (VIa), the carbocyclic analog of cytidine, was obtained in 84% yield from the pure 4-chloropyrimidinone intermediate, after the latter was prepared by deoxychlorination in carbon tetrachloride. Carbodine has antileukemic
由类似的尿嘧啶衍生物合成了胞苷,2'-脱氧胞苷和3'-脱氧胞苷的碳环类似物。该途径包括尿嘧啶衍生物的完全苯甲酰化,选择性除去连接在嘧啶环上的苯甲酰基,用二甲基甲酰胺-亚硫酰氯试剂将4-氧代转化为4-氯基以及用氯代氨酯取代氯基。甲醇氨中的氨基 当使用脱氧氯化反应的总产物时,所需的胞嘧啶衍生物常常伴随着少量的相应的N,N-二甲基胞嘧啶衍生物,可以通过离子交换色谱法除去。从纯的4-氯嘧啶酮中间体通过在四氯化碳中进行脱氧氯化制备后,以84%的收率获得了胞嘧啶核苷的类似物卡铂(VIa)。卡博定具有抗白血病,抗病毒和抗菌活性。
