A novel and efficient route for the conversion of imines and sulfonic acids into β-sultams using phosphonitrilic chloride at room temperature in dry CH2Cl2 is described. Optimization of the conditions was performed. This method is ve

Mild and efficient one-pot synthesis of β-sultams with the Vilsmeier reagent proceeded in good to excellent yield. [2 + 2] Cycloaddition of imines with sulfenes (prepared in situ) afforded the corresponding cis-β-sultams. Optimization of solvents, molar ratio of reagents,and temperature was performed. Toxic and corrosive compounds have been avoided in this novel method.
