Cerium Iv Ammonium Nitrate

AbstractStarting from readily available 2-naphthol, aldehydes, aryl and alkylamines, a variety of Betti bases were efficiently synthesized utilizing a catalytic amount of cerium (IV) ammonium nitrate (CAN) at room temperature. This protocol has advantages of high yield, mild reaction conditions, no environmental pollution, diversity of reactants and simple work up procedure.

Dihydropyridine Derivatives

Dipyrimidine-fused pyridine derivatives were synthesized using 1,3-diketone, aldehyde, different ammonium salts, and water, as the solvent. Aromatization was observed when ammonium nitrate was used as the source of nitrogen, and thus, dipyrimidine-fused pyridine derivatives were synthesized in one-pot synthetic procedure. This environmentally benign procedure leads to high yield of products (80%–90%) in a single step, with greater purity using water as the solvent.Key words: water, aromatization, dipyrimidopyridine, ammonium salts.

Cerium Iv Ammonium Nitrate

An efficient and facile synthesis of substituted pyrimidine derivatives through Biginelli type reaction was achieved in high yields via one-pot reaction of aromatic aldehydes, active methylene compounds and urea or thiourea in the presence of choline chloride- urea mixture as a deep eutectic solvent or cerium (IV) ammonium nitrate (CAN) as a catalyst at different conditions. The reaction was carried out using different ratio of CAN in different solvents to determine the optimum conditions. In addition, 2-mercapto-6-oxo- 4-(thiophen-2-yl)-1,6-dihydropyrimidine-5-carbonitrile was employed in the synthesis of pyrimidinylhydrazide and its corresponding hydrazone. The structural formula of all derivatives was confirmed and characterized by their elemental analyses and spectral data (IR, MS, 1H NMR, 13C NMR).
