A series of cinchona alkaloid‐ester derivatives was synthesized and applied to catalyze the enantioselective oxaziridination of aryl aldimines with m ‐CPBA. The ( R,R )‐oxaziridines were obtained in good yields with high enantiomeric excess (ee) values (up to 98%). Chirality 26:150–154, 2014 . © 2014 Wiley Periodicals, Inc.
