Novel 1,2,4‐triazole isonucleosides (1 and 2) were efficiently synthesized starting from D‐ribose and D‐xylose, respectively. The key steps were condensation of cyclic sulfate 8 with methyl‐1,2,4‐triazole‐3‐carboxylate and nucleophilic displacement of the tosylate 15 with methyl‐1,2,4‐triazole‐3‐carboxylate, respectively.
摘要 分别以 D-核糖和 D-木糖为原料,高效合成了新型 1,2,4-三唑异核苷(1 和 2)。关键步骤分别是环硫酸盐 8 与 1,2,4-三唑-3-羧酸甲酯的缩合和甲苯磺酸酯 15 与 1,2,4-三唑-3-羧酸甲酯的亲核置换。
