Aggarwal, V. K.; McGarrigle, E. M.; Shaw, M. A.Science of Synthesis: Stereoselective Synthesis, (20112332.

In Corey and Chaykovskyʼs second publication on the ylide-mediated epoxidation of aldehydes they demonstrated that the reaction could also be applied to imines to afford aziridines, employing either trimethylsulfoxonium methylide or trimethylsulfonium methylide, the latter providing the higher yield of 91% of aziridine 43 in the reaction of N-phenylbenzaldimine (Scheme 25).[‌75‌]
