alkylation of 8-ethylquinolines with enones or acrolein using a RhIII catalyst and a chiral carboxylic acid is described. Under mild reaction conditions, a binaphthyl-based chiral carboxylic acid enables the enantioselective cleavage of the 8-ethylquinoline C(sp3)–H bond. The obtained results demonstrate the utility of the combination of a high-valent group 9 metal catalyst and a chiral carboxylic acid for
Catalytic enantioselective directed methylene C(sp3 )-H amidation reactions of 8-alkylquinolines using a Cp*RhIII /chiralcarboxylicacid (CCA) hybrid catalytic system are described. A binaphthyl-based chiralcarboxylicacid efficiently differentiates between the enantiotopic methylene C-H bonds, which leads to the formation of C-N bonds with good enantioselectivity.
