Reactions of N‐isocyaniminotriphenylphosphorane with 2‐oxopropylbenzoate (or 2‐oxopropyl 4‐bromobenzoate) in the presence of (E)‐cinnamic acids and primary amines proceed smoothly at room temperature and in neutral conditions to afford sterically congested 1,3,4‐oxadiazole derivatives in high yields. The reaction proceeds smoothly and cleanly under mild conditions and no side reactions were observed
在(E)-肉桂酸和伯胺存在下,N-异氰亚氨基三苯基膦烷与2-氧丙基丙基苯甲酸酯(或2-氧丙基4-溴代苯甲酸酯)的反应在室温和中性条件下平稳进行,得到空间拥挤的1,3,4-恶二唑衍生物收率高。反应在温和条件下平稳,干净地进行,未观察到副反应。
