Resumo:	This paper reports a theoretical investigation of the most probable mechanism for the asymmetric aziridination of olefins by N‐aryl‐O‐acylhydroxylamines. The transition states of two possible mechanisms (Scheme 2) were studied. The transition state for pathway 2 (oxaziridine as intermediate) has a lower energy of activation than the energy of the transition state for pathway 1. The anionic transition state of pathway 2 is more stable than the neutral transition state.
