  摘要：

  胞苷与22种不同的2-O-酰氧基异丁酰氯的反应导致分离出相应的2,2'-脱水-1-（3'-O-酰基-β-d-阿拉伯呋喃糖基）胞嘧啶盐酸盐9。这些化合物，所有这些都显示出对组织培养物中的HeLa细胞具有细胞毒性，已经检查了其抗病毒和抗白血病活性。在组织培养中，对具有DNA带有8--12个碳原子的酰基的化合物，DNA病毒（牛痘和疱疹）的活性最大。小鼠对L1210白血病的活性随酰基长度的变化而显着变化，长链（C16-C22）酯具有很高的活性。胞苷与O-乙酰基水杨酰氯之间的反应为合成3'-O-Ac环C盐酸盐提供了另一种途径。

  The present invention is an efficient synthetic route to 2′,3′-dideoxy-2′,3 ′-didehydro-nucleosides from available precursors with the option of introducing functionality as needed, such as, the 2′,3′-dideoxy and 2′- or 3′-deoxyribo-nucleoside analogs as well as additional derivatives obtained by subsequent functional group manipulations. Briefly, the present invention discloses a method for the preparation of &bgr;-D and &bgr;-L-2′,3′-dideoxy-2′,3′-didehydro-nucleosides starting from appropriately substituted ribonucleosides in two, optionally three steps: Step (1) a haloacylation, such as haloacetylation, and in particular, bromoacetylation; Step (2) a reductive elimination; and optionally, Step (3) a deprotection. The haloacylation of step (1) can form the 2′-acyl-3′-halonucleoside, the 3′-acyl-2′-halonucleoside, or a mixture thereof.

  本发明提供了一种高效的合成路线，可以从可用的前体物开始合成2'，3'-二脱氧-2'，3'-二脱氢核苷，同时可以根据需要引入功能，例如2'，3'-二脱氧和2'-或3'-脱氧核糖核苷类似物以及通过后续的官能团操作获得的额外衍生物。简而言之，本发明揭示了一种制备β-D和β-L-2'，3'-二脱氧-2'，3'-二脱氢核苷的方法，从适当取代的核糖核苷开始，在两个可选的步骤中进行：步骤（1）卤代酰化，例如卤代乙酰化，特别是溴代乙酰化；步骤（2）还原消除；可选地，步骤（3）去保护基。步骤（1）的卤代酰化可以形成2'-酰基-3'-卤代核苷，3'-酰基-2'-卤代核苷或它们的混合物。

  The reactions of cytidine with 22 different 2-O-acyloxyisobutyril chlorides lead to the isolation of the corresponding 2,2'-anhydro-1-(3'-O-acyl-beta-d-arabinofuranosyl)cytosine hydrochlorides 9. These compounds, which all show cytotoxicity against HeLa cells in tissue culture, have been examined for antiviral and antileukemic activity.
