Abstract
A series of 2‐aminochromene derivatives including 2‐amino‐benzo[h] chromene, 2‐amino‐benzo [f] chromene and 2‐aminopyrano [3, 2‐h] quinolin derivatives was synthesized from arylaldehyde, malononitrile or ethyl cyanoacetate and 1‐naphthol or 2‐naphthol or 8‐hydroxyquinoline in refluxing ethyl alcohol catalyzed by KF‐Al2O3. The structures were confirmed by X‐ray analysis.Keywords
