Oxadiazole is a heterocyclic aromatic chemical compound with the molecular formula C2H2N2O. There are four isomers of oxadiazole: File:1,2,3-oxadiazole.svg|1,2,3-oxadiazole File:1,2,4-oxadiazole.svg|1,2,4-oxadiazole File:1,2,5-oxadiazole.svg|1,2,5-oxadiazole (furazan) File:1,3,4-oxadiazole.svg|1,3,4-oxadiazole 1,2,4-Oxadiazole, 1,2,5-oxadiazole, and 1,3,4-oxadiazole are known, but the 1,2,3-isomer is unstable and reverts to the diazoketone tautomer.〔''Heterocyclic Chemistry'', 3rd Edition, J. A. Joule, K. Mills, and G.F. Smith, page 452〕 The stable oxadiazoles appear in a variety of pharmaceutical drugs including raltegravir, butalamine, fasiplon, oxolamine, and pleconaril. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「oxadiazole」の詳細全文を読む スポンサード リンク
