A novelmethod for the synthesis of 1,2‐dihydro‐5‐arylnaphtho[2,1‐c][2,7]naphthyridinederivatives 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
