Abstract: o-Phenylenediamine reacts with diethylbromo malonate to form ethyl-1,2,3,4-tetrahydro-3-oxoquinoxaline-2-carboxylate 2, which reacts with hydrazinehydrate to form 3-hydroxy-quinoxaline-2-carbohydrazide 3. Compound 3 on condensation with different aromatic aldehydes gives N'-arylidene-3-hydroxyquinoxaline-2-carbohydrazides 4 which is cyclised with chloroacetyl chloride and thioglycolic acid to obtain N-(3-chloro-2-oxo-4-arylazetidin-1-yl)-3-hydroxyquinoxaline-2-carboxamides 5 and 3-hydroxy-N-(4-oxo-2-phenylthiazolidin-3-yl)quinoxaline-2-carboxamides 6 respectively. The structures of these compounds are confirmed by 1H NMR and LC-MS data.
