Efficient synthesis of chromeno[4′,3′:4,5]pyrano[3,2-c][1,8] naphthyridin-13-one derivatives has been described by domino Knoevenagel-hetero-Diels-Alder reaction of 4-hydroxy-1-phenyl-1,8-naphthyridin- 2(1H)-one with O-allylated/propargylated salicylaldehydes. The reaction occurs in a single step and is highly regio- and stereoselective giving polycyclic heterocycles in high yields.
