NHC‐catalyzed (NHC=N‐heterocyclic carbene), highly asymmetric intermolecularStetterreaction allows the atom‐economic and efficient formation of valuable α‐amino acidderivatives (see scheme); the key step is an intramolecular stereoselective protonation. For the first time, a β‐unsubstituted Michael acceptor was employed successfully in this kind of reaction, most importantly, with a broad range of
