Hydrothermal preparation and characterization of ZnFe2O4 magnetic nanoparticles as an efficient heterogeneous catalyst for the synthesis of multi‐substituted imidazoles and study of their anti‐inflammatory activity
Nanoparticles are key focus of research for a wide range of novel applications. As such, ZnFe2O4 magnetic nanoparticles were synthesized hydrothermally and charac-terized via scanning and transmission electron microscopies, powder X‐ray diffrac-tion, energy‐dispersive X‐ray and infrared spectroscopies, thermogravimetric analysis and magnetic measurements. They were used as a robust catalyst for the synthesis of a series of biologically active multi‐substituted imidazoles ... إقراء المزيد

Eco-friendly and efficiently synthesis, anti-inflammatory activity of 4-tosyloxyphenylpyrans via multi-component reaction under ultrasonic irradiation and room temperature conditions
A series of new 4-tosyloxyphenylpyranderivatives 3-11 were efficiently synthesized via one-pot, multicomponent reaction (MCRs) of 4-tosyloxybenzaldehyde 1, malononitrile and some ketonic reagents through green chemistry protocols using Ultrasonic irradiation technique or stirring in water at room temperature. All products were obtained in excellent yield, pure at low cost processing and short time. The structure of all compounds was characterized by ... إقراء المزيد
