Effective synthesis of 1,2-di-, 1,2,3-tri-, 1,2,3,3-tetraalkyldiaziridines and 1,5-diazabicyclo[3.1.0]hexanes

A versatile single-step procedure was proposed for the synthesis of the title compounds by the interaction of equimolar amounts of aliphatic carbonyl compounds, primary aliphatic amines and N-chloroalkylamines in an aprotic organic solvent in the presence of potassium carbonate.
