A novel method for the synthesis of 1,2‐dihydro‐5‐arylnaphtho[2,1‐ c ][2,7]naphthyridine derivatives via a three‐component reaction of aromatic aldehyde, naphthalen‐2‐amine, and N ‐substituted piperidin‐4‐one derivatives is described using 5 mol % iodine as catalyst. The features of this new procedure are mild reaction condition, high yield, operational simplicity, and uses available reactants. J. Heterocyclic Chem., (2009).
