Synthetic Studies of Bioactive Quinoxalinones: A Facile Approach to Potent Euglycemic and Hypolipidemic Agents

Substituted quinoxalin-2-ones have been prepared in high yields in a one-pot reaction in which a 1:1 mixture of 1,2-diaminobenzene and appropriate ethyl 2-bromoalkyl/aryl acetate is subjected to microwave irradiation in presence of DBU at 190 °C for 6 min A possible mechanism is presented.
