Substituted quinoxalinederivatives are traditionally synthesized by co‐condensation of various starting materials. Herein, we describe a novel environmentally benign in water synthetic route for the synthesis of structurally and electronically diverse ninety quinoxalines with readily available substituted o‐phenylenediamine and 1,2‐diketones using cheap and biodegradable itaconic acid as a mild acid
