have been synthesized via the three-component domino reaction of glutaraldehyde and malononitrile with a series of beta-ketoamides under microwave irradiation conditions in the presence of a catalytic amount of Et3N (10 mol%). This reaction represents the first reported process for the facile conversion of a beta-ketoamide to a hydroisoquinoline via a C-N bond cleavage reaction without the need for

and efficient one-potsynthesis of functionalized [1,8]naphthyridine derivatives via a three-component domino reaction of glutaraldehyde, malononitrile, and β-ketoamides, undercatalyst-freeconditions in an environmentally friendly medium (ethanol) is described. The main advantages of this protocol are short reaction times, practical simplicity, high yields, catalyst-freeconditions, cheap and benign
