One-pot synthesis of 2-azetidinones has efficiently been carried out in excellent yields by treatment of imines and substituted acetic acids with 3,5-dinitrobenzoyl chloride in the presence of triethylamine. The method is remarkably convenient and pure products were obtained by simple crystallization.
