Telluronium salts mediated aziridination of chiral N-tert-butylsulfinylimines: highly stereoselective synthesis of optically active vinylaziridines.

[reaction: see text] Optically active cis-2-substituted vinylaziridines are synthesized by the reaction of N-tert-butylsulfinylimines with telluronium ylides with excellent diastereoselectivity in good to excellent yields.
