Sulfuric acid heterogenized on magnetic Fe3O4 nanoparticles: A new and efficient magnetically reusable catalyst for condensation reactions

Immobilized sulfuric acid on magnetic Fe3O4 nanoparticles (Fe3O4 MNPs-OSO3H) as a new solid acid nanocomposite was successfully synthesized and its catalytic activity in a series of condensation reactions was studied. High catalytic activity, simple separation from reaction mixture by an external magnet and good reusability are several eco-friendly advantages of this catalytic system. It is noteworthy that this catalytic system is applicable to a wide range of spectrum of aromatic aldehydes, and the desired products were obtained in good to excellent yields under mild conditions. The use of ecofriendly solvents makes also this synthetic protocol ideal and fascinating from the environmental point of view.

One-pot multicomponent synthesis hexahydroquinoline derivatives in Triton X-100 aqueous micellar media

A facile and efficient synthesis of hexahydroquinoline derivatives (5a-o) was reported via a four-component condensation reaction of aldehydes, dimedone, methyl aceto acetate and ammonium acetate in the presence of Triton X-100 in water at room temperature. The use of just 20 mol % of Triton X-100 in water solvent is sufficient. The FT-IR, 19F NMR, 1H NMR, 13C NMR spectra and elemental analysis confirm the structure of the compounds.
