Application of Multi-component Reaction in Synthesis of Multi- substituted Imidazoles

Application of Green Procedure for the Synthesis of Substituted Pyrroles: Multi-component Reaction of Oxalyl Chloride

A novel, convenient and efficient approach to synthesis of pyrrole derivatives via the reaction of primary amines, alkyl propiolates and oxalyl chloride is described. The method offers several advantages including high yields of products and performing reaction in water as the solvent. 

single-step synthesis of multi-component spirobarbiturates using ionic liquids and synthesis of substituted pyridine filled with catalysts supported on solid substrate

in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...

Nano TiO2@SiO2 as an efficient and reusable catalyst for the synthesis of multi-substituted imidazoles

Nano TiO2 supported on SiO2 (Nano TiO2@SiO2) as a solid Lewis acid, was described to be an effective and reusable catalyst for one-pot three-component reaction of benzil, aryl aldehydes and ammonium acetate for the synthesis 2-aryl-4,5-diphenyl-1H-imdazoles synthesis. To explore the high efficacy of the catalytic system the four-component cyclization of benzil, aryl aldehydes, ammonium acetate ...
