An efficient access to 8-benzoylquinoline was developed by a sequential arylation/oxidation of 8-methylquinolines with aryl iodides in the presence of Pd(OAc)2. This transformation demonstrates good tolerance of a wide range of functional groups on aryl iodides, providing good to excellent yields of 8-benzoylquinolines.

A new method for building aryl aryl ketones containing heterocyclic rings through chelation-assisted C-O bond activation catalyzed by a rhodium complex has been developed. In this reaction, methyl quinoline-8-carboxylate, methyl quinoxaline-5-carboxylate, and their derivatives were reacted with an excess amount of a substituted phenyl boronic acid in the presence of a rhodium(I) complex to give substituted phenyl(quinolin-8-yl)methanone, phenylquinoxalin-5- ylmethanone, and their derivatives in medium to high yields. The current method offers a highly favorable synthetic pathway to efficiently build related drugs with an 8-benzoylquinoline core structure. This method may prove especially valuable for medicinal chemists for the late-stage introduction of versatile ketone moieties into complex scaffolds for diversity-oriented synthetic strategies.
