Abstract
The direct concurrent installation of amide and ester groups across olefin motifs represents a powerful and promising functionalization tool in organic chemistry. Herein, a ligand-free cobalt-catalyzed four-component radical relay carbonylative difunctionalization of ethylene for the synthesis of 4-oxobutanoates has been developed. Valuable C4 building blocks were produced in a highly atom-economical fashion.
