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 at100 oC was reported. The desired products were obtained in excellent yields (88-92%). Variousbenzene-1,2-diamines, and dialkyl acetylendicarboxylate were used in the traditional method.
