A method for the direct stereospecific conversion of structurally diverse mono-, di-, tri- and tetra-substituted olefins to NH, N-alkyl, N-cycloalkyl, or N-aralkyl aziridines using a hydroxylamine amination agent with transition metal catalyst. The method is operationally simple (i.e., one-pot), scalable and fast at ambient temperature.
