Chromene and its derivatives belong to a major class of natural heterocyclic compounds,
which they occur widely in edible vegetables and fruits. They frequently expose a variety of
biological and pharmacological activities. Based on the extensive researches, it has been
observed that chromene derivatives include biological activities such as antioxidant,
spamolytic, anti-HIV, anticancer, anti-anaphylactic, antibacterial activity antihypertensive,
anti-tubulin, antiviral, activator of potassium channels and inhibition of phosphodiesterase IV
or dihydrofolate reductase, etc [1-2].
Owing to the important applications of chromene derivatives, various synthetic
methodologies for these compounds have been reported. However, many of these methods
suffer from acidic media, unsatisfactory yields, longer reaction times, difficult work up,
excessive use of reagents and catalyst. It is therefore, important to find more convenient
methods for the preparation of these compounds.
In order to make the reaction simple and green and in continuation of our efforts for the
synthesis of heterocyclic compounds [3], herein, Fe3O4 nanoparticles (MNPs) under grind
condition has been successfully applied to perform the reaction of B-naphtol, malononitrile
and arylaldehyde to provide a series of chromene derivatives in excellent yields and short
reaction times.
