چکیده
an efficient synthesis of trialkyl (e)-3-(3-oxo-2-3,4-dihydro-2-(1h)-quinoxalinylidene)-prop-1-ene-1,2,3-tricarboxylate derivatives via a simple three-component reaction between benzene-1,2-diamines with dialkyl acetylenedicarboxylates in the presence of k2co3-peg catalytic system at 100 oc was reported. the desired products were obtained in excellent yields (88-92%). various benzene-1,2-diamines, and dialkyl acetylendicarboxylate were used in the traditional method. quinolines are major classes of heterocyclic compounds, which have attracted considerable attention from chemists for their large broad biological activities and amazing physical properties. furthermore, the synthesis of quinoxalines and their derivatives has received much attention from organic and medicinal chemists. as part of our current studies on the development of new routes to synthesize quinoxaline systems. the corresponding quinoxalines are useful building blocks for the construction of complex quinoxaline derivatives
