A series of 2‐aminochromene derivatives include 2‐aminobenzo‐[h]chromene and naphtha[1,2‐b;6,5‐b′]dipyrans derivatives were synthesized from arylaldehyde, malononitrile or ethyl cyanoacetate with 1‐naphthol or 1,5‐naphthalenediol in refluxing ethyl alcohol catalyzed by KF‐Al2O3. The structure of the products was confirmed by X‐ray analysis.
