Organocatalytic Enantioselective Oxidative CH Alkenylation and Arylation of N ‐Carbamoyl Tetrahydropyridines and Tetrahydro‐β‐carbolines

The first organocatalytic enantioselective CH alkenylation and arylation reactions of N ‐carbamoyl tetrahydropyridines and tetrahydro‐β‐carbolines (THCs) are described. The metal‐free processes represent an efficient and straightforward approach to a variety of structurally and electronically diverse α‐substituted tetrahydropyridines and THCs in good yields with excellent regio‐ and enantioselectivities. Preliminary control experiments provide important insights into the reaction mechanism.
