GRAPHICAL ABSTRACT ABSTRACT Reactions of N-isocyaniminotriphenylphosphorane (NICITPP) with 2-oxopropyl-1-benzenecarbothioate in the presence of aromatic carboxylic acids and primary amines proceed smoothly at room temperature (18–26°C) and in neutral conditions to afford sterically congested 1,3,4-oxadiazole derivatives in high yields. The reaction progresses smoothly and clearly under mild conditions
图形摘要摘要 N-异氰基亚氨基三苯基膦 (NICITPP) 与 2-氧代丙基-1-苯硫代碳酸酯在芳香族羧酸和伯胺存在下的反应在室温 (18–26°C) 和中性条件下顺利进行,得到空间拥挤的 1 ,3,4-恶二唑衍生物的收率很高。反应在温和条件下顺利进行,没有观察到副反应。
