Palladium-catalyzed C–H alkenylation of quinoxaline N-oxide enabled by a mono-N-protected amino acid

Abstract The efficient alkenylation of quinoxaline N -oxide was achieved via Pd-catalyzed C–H activation, using the assistance of a mono- N -protected amino acid. Further deoxygenation of the 2-styrylquinoxaline- N -oxides yielded the corresponding styrylquinoxaline derivatives.
