ResumoA mild and efficient method for the synthesis of pyrano[3,2-f]quinoline and 4,7-phenanthroline derivatives via three-component domino reaction of heterocyclic amines, aldehydes, and terminal alkyne using BF3˙OEt2 as Lewis acid catalyst is described. The features of this procedure are mild reaction conditions, good to high yields, and operational simplicity.
