    • The imines 2a-i were prepared by reaction of the corresponding amine with 1.0 equiv of aldehyde in methylene chloride at rt in the presence of anhydrous sodium sulfate. After filtration, the solvent is removed and the imine purified.

    • note
    • General procedure for the synthesis of aziridines: To a solution of imine (0.35 mmol) and molecular sieves (100 mg) in methylene chloride (2 ml), 0.035 mmol of the catalyst was added at 0 °C. Ten minutes after a solution of DIDAMP (0.52 mmol) in methylene chloride (1 ml) was added and the reaction mixture was stirred at the same temperature until the imine was consumed. The solvent was eliminated under reduced pressure. The crude product was purified by flash chromatography on silica gel (20-30% ethyl acetate/hexane).
