A new asymmetric approach to assemble cis-vinyl aziridines is reported. A reaction of strategically substituted dienolates, decorated with a γ-leaving group, with chiral sulfinimines afforded chiral vinyl aziridine products in good to excellent yields. This is the first systematic study toward the realization of a useful asymmetric vinylogous aza-Darzens reaction. The reaction is initiated by a syn-selective addition, affording cis-vinyl aziridine products after displacement of bromide. The low syn-diastereoselectivity is attributed to competing retro-Mannich pathways.
