Stereoselective synthesis of 2,3-di- and 2,2′,3-tri-substituted aziridines in good yields and excellent diastereoselectivities are achieved through aza-Darzens reactions of a range of tert-butanesulfinyl aldimines and ketimines with ethyl bromoacetate.

A novel asymmetric radical cyclization of alkenes via stereospecific homolytic substitution of sulfonamides was established, allowing ready access to a diversity of cyclic sulfinamides with excellent stereocontrol. The protocol offers a robust tool for the synthesis of chiral sulfinamides and their derivatives.
