(preparative separations; racemizations of enantiomeric diaziridines)

Sažetak
Preparative separations or enrichments of enantiomers of diazidines l, 2, and 5 were achieved by liquid chromatography on triacetylcellulose, ( + )– l and ( +)-2 being isolated almost pure. Enantiomeric purities were determined by 1H NMR in the presence of the optically active auxiliary compound ( + )-Eu(hfbc)3. The barriers to nitrogen inversion in 1 and 4 were determined and its lower limit in the nitrogen unsubstituted diaziridine 3 was estimated.
