A catalytic amount of camphorsulfonic acid indeed facilitated the reaction of 1b and N -Boc imine smoothly, although the aziridine was obtained in a racemic form. In our preliminary experiments, neither chiral phosphoric acid nor dicarboxylic acid (see refs 6 and 7) promoted the reaction even at room temperature.
