A friendly benign, green, rapid and facile strategy for synthesis a series of arylquinoxalines was achieved by condensation of aromatic 1,2-diamines with arylglyoxals under clay-catalyzed as an inexpensive and eco-friendly catalyst using grindstone chemistry. Significant decreases in reaction times and high yields have been observed by this green chemistry approach in comparison with previously...

Multicomponent condensation of 1-naphthol, malononitrile, and arylglyoxals in the presence of Mg-Al hydrotalcite under solvent-free MicroWave (MW) conditions gave a new series of 2-amino-4-aroyl-4H-benzo[h]chromene-3-carbonitriles in high yields (70-89%). The structure of all products was elucidated by their...

In this research, 15 novel derivatives of the thiazolactone skeleton were synthesized using Erlenmeyer–Plöchl reaction procedure. Glycine, alanine and leucine amino acids used to make dithiocarbamate precursor by reacting with carbon disulfide benzyl chloride. Obtained underwent formation in presence acetic anhydride then condensed arylglyoxals as condensing carbonyl group source. Products char...
