5‐disubstituted‐1,3,4‐oxadiazole and 1,2,4‐triazole derivatives were synthesized by heterocyclization of acid hydrazide 1 and thiosemicarbazide derivative 2. Furthermore, the acyclic C‐nucleoside analogs were prepared by cyclization of their corresponding sugar hydrazones by reaction with acetic anhydride. The antimicrobial activity of the prepared compounds was evaluated and some of the synthesized compounds
通过酰肼1和硫代氨基脲衍生物2的杂环化反应,合成了一系列新的2,5-二取代-1,3,4-恶二唑和1,2,4-三唑衍生物。此外,无环C-核苷类似物是通过与乙酸酐反应将其相应的糖环环化而制得的。评价了所制备化合物的抗微生物活性,并且一些合成的化合物显示出对真菌的良好活性。
