Abstract
MOF-5 has been employed as a powerful catalyst for the preparation of 2-amino-4H-chromene. A wide variety of aromatic aldehydes was condensed with malononitrile and 2-naphthol under mild and solvent-free conditions in the presence of the trace amount of catalyst. A variety of 2-amino-4H-chromene can be obtained in good to excellent yield up to 95% in relatively short time reaction and easy workup.
