    2-Hydroxyethyl-1-ammonium 3-hydroxypropane-1-sulfonate ‘HAHS’ was synthesized as a novel ionic liquid and characterized by various techniques. ‘HAHS’ ionic liquid was efficiently applied as a multifunctional promoter for the three-component synthesis of 2-amino-3-cyano-4H-pyrans. The 2-amino-3-cyano-4H-pyrans were produced not only in high to excellent yields but also no toxic solvent or catalyst was used. ‘HAHS’ ionic liquid was recovered and reused four times without the considerable decreasing in its activity. The effect of hydroxyl groups in the structure of ‘HAHS’ ionic liquid on its catalytic activity was studied. Moreover, the biodegradability potential of the ionic liquid was examined using the 5-day biological oxygen demand closed bottle test and the results showed that ‘HAHS’ has remarkable biodegradability potential.

    Magnetically separable Fe3O4 nanoparticles were used as an environmental friendly catalyst for the synthesis of mono- and bis-tetrahydro-4H-chromene and mono- and bis-1,4-dihydropyridine derivatives via three-component reactions of aromatic aldehydes and malononitrile with cyclic β-dicarbonyls or cyclic β-enaminoketones respectively. These reactions were carried out in EtOH and at reflux. Fe3O4 nanoparticles can be magnetically separated from the reaction mixture by a magnet and recycled without significant loss of catalytic activity.
