Methyl 5-carboxamido-4-hydroxy-3(β-D-ribofuranosyl)-2-thiophene carboxylate 2a and the corresponding 2,5-thiophene dicarboxamide 2b, two new analogues of the antiviral compound pyrazofurin, were synthesized. A base mediated condensation method with dimethyl thiodiacetate and methyl 2(2,3,5,-tri-O-t-butyldimethylsilyl-β-D-ribofuranosyl)-2-oxoacetate 5 was used. The structure of these compounds and their
合成了5-甲酰胺基-4-羟基-3(β-D-呋喃呋喃糖基)-2-噻吩羧酸甲酯2a和相应的2,5-噻吩二甲酰胺2b,这是抗病毒化合物吡唑并呋喃的两个新类似物。使用了一种由硫代二乙酸二甲酯和2(2,3,5,-三邻丁基丁基二甲基甲硅烷基-β-D-呋喃呋喃糖基)-2-氧代乙酸甲酯5进行的碱介导的缩合方法。这些化合物及其中间体的结构用光谱法确定。
