Access to NH-aziridine-2-carboxamides through Davidsen acylimidodicarbonate activation

Abstract Acylimidodicarbonates obtained from aziridine-2-carboxamides through Davidsen bis-Boc activation react with amine nucleophiles under mild conditions to form tertiary aziridine-2-carboxylic acid amides. NH aziridine-2-carboxylic acid amides were obtained by hydrogenolythic deprotection of N-Cbz derivatives.
