Efficient Aziridination of α,β-Unsaturated Ketones with O-(2,4-Dinitrophenyl)-hydroxylamine.

Abstract The aziridination of α,β-unsaturated ketones with O-(2,4-dinitrophenyl)-hydroxylamine and tertiary amine was developed. trans-Aziridines were obtained exclusively in good yields. The reaction is proposed to occur via an aminimide intermediate.
