ABSTRACT One-pot mild synthesis of 2-azetidinones was carried out by the reaction of imines and carboxylic acids in dry dichloromethane at room temperature using diphosphorus tetraiodide. It was also applied for synthesis of 3-spiro-2-azetidinones. The synthesized compounds were characterized by analytical and spectral (infrared, 1H NMR, 13CNMR, and elemental analysis) data.
