This approach offers many advantages such as good product yields, various products, short reaction time, easy isolation of products, facile purification and environmentally benign reaction conditions. Graphical Abstract Synthesis of some glycoluril, imidazolidine-2-one, imidazole-2-one and imidazole-2-thiol derivatives was carried out by condensation reaction of urea derivatives with α-diketone compounds in the presence of trimethylsilyl chloride (TMSCl) catalyst under solvent-free conditions.
