The vinyl phosphonate derivatives of uridine, cytidine, and cytosine arabinoside (ara-C) have been prepared through oxidation of appropriately protected nucleosides to the 5' aldehydes and Wittig condensation with [(diethoxyphosphinyl)methylidine]triphenylphosphorane. Dihydroxylation of these vinyl phosphonates with an AD-mix reagent generated the new 5',6'-dihydroxy-6'-phosphonates. After hydrolysis
尿苷,胞苷和胞嘧啶阿拉伯糖苷(ara-C)的乙烯基膦酸酯衍生物是通过将适当保护的核苷氧化成5'醛并与[(二乙氧基膦基)亚甲基]三苯基磷烷进行Wittig缩合反应制得的。用AD-mix试剂将这些乙烯基膦酸酯二羟基化,生成新的5',6'-二羟基-6'-膦酸酯。在膦酸酯和各种保护基水解后,测试了六种膦酸作为核苷酸单磷酸激酶底物的能力以及对K562细胞的毒性。
