An　efficient　procedure　for　the　synthesis　of　caffeoyl-　and　galloyl-containing　beta-diketoacid　derivatives　linked　by　arylamide　was　reported　by,　in　the　key　step,　dissolving　the　corresponding　phenyl　methyl　ketone　in　THF/DME　in　the　presence　of　NaOMe　as　base　and　dimethyl　oxalate　as　oxalylation　reagent,　and　then　separating　the　sodium　ketoenolate　ester.　The　resulting　beta-diketoacids　underwent　further　condensation　reaction　with　o-phenylenediamine　to　generate　quinoxalone　derivatives　in　good　yield,　rather　than　2-benzimidazol.　The　preliminary　ion　binding　properties　of　quinoxalone　derivatives　were　also　investigated.　UV-Vis　spectra　showed　that　these　compounds　could　selectively　recognize　Cu2+　ion　in　ethanol　and　form　a　1　:　2　complex.
