An unprecedented protocol for the synthesis of 1,2,4-oxadiazoles from carbamates has been developed by employing nitriles as both substrates and solvents. This one-pot procedure achieves the formation of C═N bonds via TFA-mediated [3+2] annulation. A series of 1,2,4-oxadiazoles are synthesized in moderate to good yields.
通过使用腈作为底物和溶剂,开发了一种从氨基甲酸酯合成 1,2,4-恶二唑的前所未有的方案。这一一锅法通过 TFA 介导的 [3+2] 环化实现了 C=N 键的形成。以中等至良好的收率合成了一系列 1,2,4-恶二唑。
