## Abstract Enantiomeric diaziridines have been partially separated by chromatography on triacetlycellulose. (−)‐**2**, (+)‐**4**, and (−)‐**4** were obtained almost pure, enantiomeric purities (Table 1) being measured by ^1^H NMR in the presence of optically active additives. The same procedure wa
