A C-nucleoside compound, 2,4-dichloro-5-(2,3,5-Tri-O-acetyl-.beta.-D-Ribofuranosyl)pyrimidine, useful as a primary starting material in the synthesis of various C-nucleoside compounds having antitumor, antiviral and/or antibacterial activity. A structural formula is as follows: ##STR1## The location of the 2,4-dichloro members on the heterocycle, with the active sites of the carbohydrate being blocked, provides an intermediate compound well adapted for a variety of nucleophilic substitutions. Such procedures have yielded several novel analogs of known pyrimidine nucleosides found in RNA, as well as other compounds which have demonstrated chemotherapeutic utility.
一种C-核苷化合物,2,4-二氯-5-(2,3,5-三-O-乙酰基-β-D-核糖呋喃糖基)嘧啶,可用作合成具有抗肿瘤、抗病毒和/或抗菌活性的各种C-核苷化合物的主要起始物质。其结构式如下:##STR1## 2,4-二氯取代基位于杂环上,糖类活性位点被阻断,提供了适用于各种亲核取代的中间体化合物。这些方法产生了几种新型的RNA中已知的嘧啶核苷化合物的类似物,以及其他已经展示出化疗效用的化合物。
