New 2,5‐disubstituted 1,3,4‐oxadiazole derivatives bearing C‐furyl glycoside moieties and their sugar hydrazone as well as their per‐O‐acetyl derivatives were synthesized starting from ethyl 2‐[5‐(3,4‐dihydroxytetrahydrofuran‐2‐yl)‐2‐methylfuran‐3‐yl]‐2‐oxoacetate. Heterocyclization of the sugar hydrazones using acetic anhydride afforded the corresponding oxadiazoline acyclic C‐nucleosides. The antimicrobial
从乙基2- [5-(3,4-二羟基四氢呋喃)开始合成带有C-呋喃糖苷部分的新2,5-二取代的1,3,4-恶二唑衍生物及其糖及其过O-乙酰基衍生物-2-基)-2-甲基呋喃-3-基] -2-氧代乙酸酯。使用乙酸酐对糖进行杂环化,得到了相应的恶二唑啉无环C-核苷。抗菌活性评估表明,许多合成的化合物均显示出中等至较高的抗菌活性。J.杂环化学。(2011)
