기타언어초록

The 1:1 imine intermediate generated by the addition of primary amine to chloroacetone is trapped by N-isocyaniminotriphenylphosphorane in the presence of (E)-cinnamic acids and the corresponding iminophosphorane intermediate was formed. Disubstituted 1,3,4-oxadiazole derivatives are formed via intramolecular aza-Wittig reaction of the iminophosphorane intermediate. The reactions were completed in neutral conditions at room temperature. The disubstituted 1,3,4-oxadiazole derivatives were produced in excellent yields.
