Sequential Annulation Domino Reaction of Sulfur Ylides and α,β-Unsaturated Cyclic Ketimines: Synthesis of Cyclic 2‑Alkenyl Aziridines

Abstract

A sequential annulation domino reaction of sulfur ylides and α,β-unsaturated cyclic ketimines for the construction of cyclic 2-alkenyl aziridines has been developed. Readily accessible starting materials, a one-pot procedure, excellent functional group compatibility, and mild conditions make this transformation a powerful tool for the synthesis of cyclic 2-alkenyl aziridines
