    Oxadiazole 衍生物在雜環分子的合成應用
    (2021) 劉若謙; Liu, Jo-Chien
    本文以研究 3-substituted-5-(trifluoromethyl)-1,2,4-oxadiazole 作為 1,3-dipole 分子 與 1,3-dipolarophile 分子 3-dimethylaminopropenones 於金屬鹽的催化下進行 [3+2] 環化反應,並應用於合成 4-acyl-2-substituted imidazole。5-(trifluoromethyl)-1,2,4-oxadiazole 是利用amidoxime 與 TFAA在Et3N 作為鹼的條件下進行取代反應合成。研究結果顯示,5-(trifluoromethyl)-1,2,4-oxadiazole 與 3-dimethylaminopropenones 可成功合成不同苯環推拉電子基團取代的 4-acyl-2-arylimidazole 衍生物。
