Abstract

An efficient protocol to synthesize 3-alkylated quinoxalin-2(1H)-ones through photocatalytic decarboxylation coupling reactions of quinoxalin-2(1H)-ones with N-hydroxyphthalimide ester was developed. The control experiment showed that a radical was involved in this transformation. This approach provides an alternative way to obtain various valuable corresponding products in moderate-to-good yields.
