Synthesis of 1,3,5-Triazabicyclo[3.1.0]hexanes and the New Heterocyclic System 1,3,6-Triazabicyclo[3.1.0]hexane

The conditions necessary for the condensation of 1,2-unsubstituted diaziridines 1 with CH₂O and NH₃, and also with CH₂O and AlkNH₂, into the corresponding 1,3,5-triazabicyclo[3.1.0]hexanes have been found; 1,3,6-triazabicyclo[3.1.0]hexanes, the primary representatives of the new heterocyclic system, were obtained by intermolecular α-aminomethylation of 1 and 1-alkyldiaziridines 2.
