An Efficient Synthesis of Benzylamino Coumarin Derivatives via Three-component Coupling of 4-hydroxycoumarin, Aromatic Aldehyde and Cyclic Secondary Amine Catalyzed by CuO Nanoparticles
A green and efficient one-pot synthesis of benzylamino coumarin derivatives was conducted by a three-component condensation of 4-hydroxycoumarin, cyclic secondary amine, and aromatic aldehyde in the presence of CuO nanoparticles (NPs) as a heterogeneous catalyst in water at room temperature.
full textAn efficient synthesis of α,α'-benzylidene bis(4-hydroxycoumarin) derivatives catalyzed by Tl2O3 nanoparticles
In this work, we attempted to synthesize thallium (III) oxide nano structures by direct thermal decomposition using thallium I phenylsuccinic acid coordination polymer [Tl(PsucH)]n as a precursor. Also, Tl2O3 nanoparticles have been characterized by scanning electron microscopy (SEM), X-Ray powder diffraction (XRD) and IR spectroscopy and then we report a simple and efficient method for the syn...

A green and efficient one-pot three component reaction of 4-hydroxycoumarin or 1,3-dimethylbarbutyric acid, aryl glyoxals and amides (thioacetamide) has been developed in the presence of BF3- SiO2 nanoparticles in water. This method has several advantages such as high to excellent product yields in short reaction time, atom economy, environment friendly, reusable catalyst and no need for chroma...
full textSynthesis of quinazolines via CuO nanoparticles catalyzed aerobic oxidative coupling of aromatic alcohols and amidines.
CuO nanoparticles were found to be efficient catalysts for the synthesis of quinazoline derivatives; twenty-four products were obtained with good to excellent yields via reaction of N-arylamidines and aromatic aldehydes or benzyl alcohol in air. Neither a base nor an organic oxidant was necessary, and CuO nanoparticles can be recycled without a significant decrease in catalytic activity.
