1,3,4-oxadiazole derivatives constitute a group of biologically important compounds that have been used as analgesic, anti-inflammatory, antibacterial, antifungal, antispasmodic, or psychotropic drugs in addition to their role plant growth regulation and monoamine oxidase inhibition. This study focused on the use microwaves synthesis oxadiazole containing thiazolidinediones, which are promising...

      A new series of thiazolidinedione derivatives were synthesized. The structures of these compounds were established by means of IR, 1H-NMR and elemental analysis. All of the compounds were screened for antidiabetic activity on albino rats. Most of the compounds showed significant antidiabetic activity when compared with the standard drug glibenclamide.

Combination of the surfactant-free nonaqueous sol–gel approach with the microwave technique makes it possible to synthesize Fe3O4, CoFe2O4, MnFe2O4, and NiFe2O4 nanoparticles of about 5–6 nm and with high crystallinity and good morphological uniformity. The synthesis involves the reaction of metal acetates or acetylacetonates as precursors with benzyl alcohol at 170 C under microwave irradiatio...

Ultra-fast and large-quantity (grams) synthesis of one-dimensional ZnO nanowires has been carried out by a novel microwave-assisted method. High purity Zinc (Zn) metal was used as source material and placed on microwave absorber. The evaporation/oxidation process occurs under exposure to microwave in less than 100 s. Field effect scanning electron microscopy analysis reveals the formation of hi...

The increasing requirements for the environmental protection have resulted in the search for more effective, inexpensive and ecologically safe solutions. Zeolite is one of the alternatives, which due to their peculiar structure are widely used for various environmental processes. The demand for an easily accessible and inexpensive source of zeolite has raised interest in synthesis of these mine...

SnO nanoparticles were synthesized using microwave–assisted hydrothermal method. It was noticed that at 300 and 600 watt microwave power, SnO formed and remained in the tetragonal phase. At 900 watt, SnO2 started appearing and a mixture of SnO and SnO2 phases coexisted. The particle size varied from ~2 to ~13 nm at 300 to 900 watt radiation power. The UV-V absorption spectra showed the excitoni...

A modular, one-pot, two-step, four-component synthesis of polysubstituted 1,3-oxzolidines is described. The method comprises two linked domino processes: an organocatalyzed domino reaction of alkyl propiolate and an aliphatic aldehydes and a microwave-assisted amine addition cyclization domino process. An alternative modular, one-pot, three-step, four-component synthesis has also been developed...
