Atom economy and esters: compatible now! The first catalytic insertion of a CC bond into an acyl CO bond was achieved using rhodium catalysts (see scheme). The products are β‐alkoxy ketones with a fully substituted carbon center. Quinoline chelating groups were employed to stabilize the Rh‐alkoxide intermediate.

acyl substituent across an alkene, oxyacylation of alkenes, using rhodium catalyzed C–O bond activation of an 8-quinolinyl ester is described. Our unsuccessful attempts at intramolecular carboacylation of ketones via C–C bond activation ultimately informed our choice to pursue and develop the intramolecular oxyacylation of alkenes via quinoline-directed C–O bond activation.
