A Pd(II)-catalyzed enantioselective C—H olefination of 2-(arylsulfinyl)pyridines through kinetic resolution is developed. A wide range of chiral sulfoxides were prepared in good to high yields and selectivity (up to 99% ee, s-factor of up to 200) under mild conditions using cheap and commercially available L-pGlu-OH as chiral ligand. This protocol is easy to scale-up and compatible with various acrylates bearing core structures of natural products.

Key words: kinetic resolution, C—H activation, enantioselective, chiral sulfoxide
