A ZnCl2-catalyzed diastereoselective Joullié-Ugi three-component reaction from 2 H-azirines, isocyanides, and carboxylic acids was established. The protocol allows the preparation of highly and diversely functionalized N-acylaziridine-2-carboxamide derivatives in up to 82% isolated yields. Moreover, the applicability of N-acylaziridines is demonstrated through a variety of transformations.
