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

The enantioselective alkenylation and arylation of tetrahydro-β-carbolines with boronates is presented using a metal free process in the presence of tartaric acid derivative as organocatalyst and DDQ as the oxidant.
