Abstract :
In this work, a simple and economical procedure for the synthesis of spiro-4H-pyran
derivatives has been found through the three-component, one-pot condensation of
isatin/acenaphthequinone, malononitrile and different reagents including 1, 3-dicrbonyl
compounds, naphthol and 4-hydroxycumarin under thermal and solvent-free conditions
in the presence of Fe2O3 as an efficient catalyst. The major advantages of this methodology are
mild reaction conditions, eco-friendly, environmentally benign, non-toxic and inexpensive catalyst,
experimentally simplicity, good yields and short reaction times.
