Lewis Acid-Catalyzed Diastereoselective Synthesis of Multisubstituted N-Acylaziridine-2-carboxamides from 2H-Azirines via Joullié–Ugi Three-Component Reaction (doi: 10.1021/acs.joc.7b03189)
Avidin’s Medicinal Chemistry Department developed and established an innovative protocol for a ZnCl2-catalyzed diastereoselective Joullié-Ugi three-component reaction from 2 H-azirines, isocyanides, and carboxylic acids. The protocol allows the preparation of highly and diversely functionalized N-acylaziridine-2-carboxamide derivatives in up to 82% isolated yields. Additionally, the applicability of N-acylaziridines is demonstrated through a variety of transformations. This advanced protocol can be accessed in our peer reviewed publication.
