A new series of potential inhibitors of DNA topoisomerase II were synthesized from facile materials (aromatic aldehydes, Meldrum’s acid and 2-hydroxynaphthalene-1,4-dione) under microwave irradiation. The method provides a valuable tool in designing new and more potent cytotoxic analogues. This procedure is advantageous both economically and environmentally.
herein a newmethod for the synthesis of 4-aryl-3,4-dihydro-2H-benzo[g]chromene-2,5,10-triones 4 that proceeds in good yields (74–86%) and mild reaction conditions between readily available 2-amino-4-aryl-5,10-dioxo-5,10-dihydro-4H-benzo[g]chromene-3-carbonitriles 1, and formic acid (88%), at reflux for 6 h. In addition, we have also studied the antioxidant activities using DPPH and total TAC methods. GRAPHICAL
