Abstract

A series of 2,8-diamino-4,10-diaryl-di-γ-pyrano[2,3-a;2',3'-f]naphthalene-3,9-dicarboxylate de-rivatives have been synthesized by the reaction of aromatic aldehyde, cyanoacetate and 1,5-naphthalenediol in EtOH at 80 ℃ catalyzed by KF/Al₂O₃. The notable features of this procedure are mild reaction conditions, good yields and operational simplicity. The structures of the products were characterized by IR, ¹H NMR spectra and elemental analysis, and 4h was further con-firmed by X-ray diffraction analysis.

Key words: 2',3'-f]naphthalene, KF/Al₂O₃, synthesis, di-γ-pyrano[2,3-a
