An efficient and confluent approach for the synthesis of novel 3,4-dihydro-2H-naphtho[2,3-e][1,3]oxazine-5,10-dione derivatives by a three component reaction in ionic liquid

“…1 Also 1,4-naphthoquinone is a raw material for various pharmaceutical and agrochemical industries. Its derivatives exhibit biological responses such as antiallergic, 2 antithrombotic, 3 antiviral 4 apoptosis, 5 lipoxygenase inhibitors, 6,7 anti-ringworm 8 and also human DNA topoisomerase I and II inhibitors. 9 The two carbonyl groups present in 1,4-naphthoquinone behave as crucial chromophore that accounts for its bioactivities owing to their ability to accept electrons.…”
