Dihydro-3H-chromeno[3,4-b][4,7]phenanthrolin-3-one and chromeno[4,3-b]pyrano[3,2-f]quinolin-3(13H)-one derivatives have been synthesized by aza-Diels-Alder reaction of O-propargylated salicylaldehyde with 6-aminoquinolone and 6-aminocoumarin respectively. The reaction occurs in a single-step operation and provides potentially bioactive polycyclic heterocycles in high yields.
