Synthesis of an assembly of structurally importantN-H- andN-substituted acridine-1,8-diones by CAN (ceric ammonium nitrate) catalysed one-pot four-component reaction of electron-deficient and electron-rich aromatic aldehydes and aromatic amines or ammonium acetate and dimedone or cyclohexyl-1,3-diones at 26°C under sonic condition is reported. The method is clean and energy efficient as it uses a greener method and an eco-friendly catalyst.

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).

This work reports synthesis of ten novel derivatives of 5-(1-(substituted phenyl)-4,5-diphenyl-1H-imidazol-2-yl)-4-methylthiazole 5(a–o). The reaction of benzil, primary aryl amines, 4-methylthiazole-5-carbaldehyde and ammonium acetate was carried out in one pot in the presence of eco-friendly catalyst Ceric ammonium nitrate in solvent ethanol to give final compounds. The structures of the synthesized compounds were confirmed by spectral characterization such as IR, 1H-NMR, 13C-NMR and mass spectral studies.

Operational Simplicity

A series of tetrahydrobenzo[c]acridinone derivatives have been prepared by a one-pot fourcomponent reaction of 1-naphthol, aromatic aldehydes, dimedone, and ammonium acetate in aqueous media using a catalytic amount of titanium dioxide nanoparticles (TiO2 NPs). The advantages of this novel protocol include the excellent yields, operational simplicity, short reaction time, easy work-up, reusability of the catalyst and an environmentally friendly procedure.
