A Straightforward Approach toward Multifunctionalized Aziridines via Catalyst-free Three-component reactions of α-Diazoesters, Nitrosoarenes and Alkynes.

A straightforward, catalyst-free atom- and step-economical approach for the synthesis of multisubstituted 1-arylaziridine-2-carboxylates via one-pot three-component reactions of α-diazoesters, nitrosoarenes and alkynes has been described. This method could provide the facile access to a variety of multifunctionalized aziridines in up to 91% yields under mild reaction conditions, and features the catalyst-free strategy, use of cheap and readily accessible starting materials.
