Abstract During studies of aziridination of α, β-unsaturated amides with diaziridine, we found that we could prepare both the cis-and trans-aziridinecarboxamides by choosing an appropriately substituted diaziridine. While 3-monosubstituted diaziridine 2 was suitable for the trans-selective aziridination, employment of 3, 3-dialkyldiaziridine 1 resulted in the formation of cis-aziridine carboxamides, irrespective of the geometry of the substrate ( ...
