Organocatalytic Asymmetric C–H Vinylation and Arylation of N-Acyl Tetrahydroisoquinolines

The first organocatalytic enantioselective oxidative C-H functionalization of N-acyl tetrahydroisoquinolines with vinyl and aryl boronates promoted by a chiral Brønsted 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.
