In the present methodology, we have reported the synthesis of substituted phenyl quinoxaline derivatives by using 1,2-phenylenediamines and αtosyl ketones in presence of L-Proline as a catalyst and dichloromethane as solvent. This methodology is useful for the synthesis of quinoxaline derivatives with high yields..
