The first organocatalyticenantioselectiveCHalkenylation 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

The first organocatalytic enantioselective oxidative C-H functionalization of N-acyl tetrahydroisoquinolines with vinyl and aryl boronates promoted by a chiral Bronsted acid is described. This metal-free process tolerates a wide range of electronically varied N-acyl tetrahydroisoquinolines and structurally diverse boronates with good to excellent enantioselectivities.
