substituents on the ester side chains (4--16) have been synthesized. The synthesis of these diesters involved the reaction between cytidine and the corresponding acid anhydride or acid chloride in the presence of boron trifluoride etherate. Similar reaction of bis(cytidine 5'-)suberate (21) with pivaloyl chloride gave bis[2,2'-anhydro-1-(3'-O-pivaloyl-beta-D-arabinofuranosyl)cytosine 5'-]suberate dihydrochloride
合成了在酯侧链(4--16)上带有官能取代基的2,2'-脱水-1-(β-D-阿拉伯呋喃糖基)胞嘧啶盐的一系列3',5'-二酯。这些二酯的合成涉及胞苷和相应的酸酐或酰氯在三氟化硼醚化物的存在下的反应。双(胞苷5'-)硬脂酸酯(21)与新戊酰氯的类似反应,得到双[2,2'-脱水-1-(3'-O-新戊酰-β-D-阿拉伯呋喃糖基)胞嘧啶5'-]硬脂酸酯二盐酸盐(22)。该反应还可以扩展为由5'-胞苷酸一步合成2,2'-脱水-1-(β-D-阿拉伯呋喃糖基)胞嘧啶5'-磷酸(24)的3'-酯。已经检查了这些化合物在BDF1小鼠中对L1210白血病的抗肿瘤活性。腹膜内给药时,具有长链羧酸(4c,7c,12和24d)的二酯表现出高活性。口服给药时,化合物24d表现出中等活性。
