Catalytic enantioselective directed methylene C(sp 3 )−H amidation reactions of 8‐alkylquinolines using a Cp*Rh III /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.
