Abstract Reaction of sulfurylides with a series of aryl substituted chiral nonracemic sulfinyl imines afforded the corresponding aziridines in good yields with good stereoselectivity. The sulfurylides were generated by the thermally induced decarboxylation of carboxymethylsulfonium betaines. A drop in the diastereomeric ratio was observed when going from electron-deficient to electron-releasing aryl
