ChemInform Abstract: Enantioselective Intramolecular Hydroacylation of Unactivated Alkenes: An NHC‐Catalyzed Robust and Versatile Formation of Cyclic Chiral Ketones.

Abstract The NHC‐catalyzed hydroacylation of different types of unsaturated aldehydes (I), (III), (V), and (VII) gives cyclic ketones with quaternary α‐stereocenters in good yields and with high enantioselectivities.
