Catalytic Enantioselective Methylene C(sp3 )-H Amidation of 8-Alkylquinolines Using a Cp*RhIII /Chiral Carboxylic Acid System.

Catalytic enantioselective directed methylene C(sp3 )-H amidation reactions of 8-alkylquinolines using a Cp*RhIII /chiral carboxylic acid (CCA) hybrid catalytic system are described. A binaphthyl-based chiral carboxylic acid efficiently differentiates between the enantiotopic methylene C-H bonds, which leads to the formation of C-N bonds with good enantioselectivity.
