diaziridine 2c is rearranged in these conditions with ring-expansion. Complete asymmetric transformation has been found to take place on the formation of the solid phase of diastereomers 2d and 2j, and a closed cycle of diastereomeric transformations has been accomplished. Diaziridine 2g with chiral centres only at the nitrogen atoms has been obtained with the optical purity of 85.5% by resolution via
