Enantiomerically Enriched Aziridine‐2‐carboxylates via Copper‐Catalyzed Reductive Kinetic Resolution of 2H‐Azirines

Angewandte Chemie, Volume 137, Issue 26, June 24, 2025.
Kinetic resolution by copper hydride catalyzed reduction of 2H‐azirines secured optically enriched N‐H aziridine‐2‐carboxylates with excellent diastereoselectivity (>20:1) and good enantioselectivity (up to 94% ee). DFT calculations and non‐covalent interaction analysis established the reaction pathway and revealed two key non‐covalent interactions ...
