| Abstract: | The synthetic scope of the reaction of primary amines with α,β-dibromochalones to form aroylaziridines is explored and found to require at least one hydrogen on the α-carbon of the amine. Fourteen new epimeric l-alkyl-2-aryl(alkyl)-3-aroylaziridines are synthesized accordingly. Next, representative aroylaziridines are investigated by infra-red spectroscopy in solvents of ambient polarity to assess the relative populations of the gauche and cisoid conformers present in the (Z)-(cis) series. |
