A new one-pot procedure for the efficient synthesis of novel 3,4-dihydrocoumarin derivatives using commercially available substituted 2-hydroxybenzaldehydes, Meldrum’s acid, and isocyanides by a three-component condensation reaction in dichloromethane at room temperature without using any catalysts and activation was developed.
Meldrum's acid catalyzed the reaction of tetracyanoethylene with aromatic, heteroaromatic, and conjugated aldehydes led to arylidenemalononitrile in water in good yields at 80 degrees C. The work-up of reactions is very simple and the crude products are sufficiently pure to be used without further purification. The procedure provides an alternative method… (More)
Magnetic nanoparticles (MNPs) were prepared by co-precipitation of Fe+3/Fe+2 (2:1; molar ratio) with a mean size of 40 ± 5 nm. Scanning electron microscopy, dynamic light scattering, X-ray diffraction, vibrating sample magnetometer and thermogravimetric analysis were used to characterise the MNPs. The MNPs and also hydroxylated nonporous glass beads were… (More)
