Secondary and primary aliphatic amines 2 form regioselectively N,N'-substituted 1,1-dimethylethylenediamines by reaction with activated 2,2-dimethylaziridines 1.The kind of activation (X in 1), determines the mode of ring opening: X = sulfonyl gives structure 3, X = acyl or 2,4-dinitrophenyl structure 4. - Keywords: 2,2-Dimethylethylenediamines, Activated 2,2-Dimethylaziridine, Nucleophilic Ring Opening, Steric Hindrance, Amines
