A catalyst-free multicomponent reaction capable of affording a wide range of eighteen novel chromeno[4,3-b]quinolone derivatives (6a–6r) via one-pot two-step domino protocol, in ethylene glycol is reported. Catalyst-free conditions along with green solvent system make the process eco-friendly as well aseconomical. High yields of the products were obtained in short reaction times by forming three new bonds and one stereocenter in a single operation. The salient features of the present protocol are short reaction times, eco-friendly solvents, high yields and easy work-up procedure.
