| 摘 要： | A series of 2-aminochromene derivatives including 2-amino-ben-zo h ] chromene, 2-amino-benzo f ] chromene and 2-amino-pyrano 3,2-h ]quinolin derivatives was synthesized from aryl-aldehyde, malononitrile or ethyl cyanoacetate and 1-naphthol or 2-naphthoi or 8-hydroxyquinoline in refluxing ethyl alcohol cat-alyzed by KF-Al2O3. The structures were confirmed by X-ray analysis.
