This paper mainly described the new instruments of microwave-promoted organic synthesis which were appraised, and several microwave-assisted synthetic reactions, such as esterification reaction, orthogonal experimental design and fentanyl synthetic reactions. In comparison with traditional methods of organic synthesis, microwave-assisted chemistry could make high-speed processing of chemical tr...

This paper focused on a simple approach for synthesis of molybdenum oxide (MoO3) nanoparticles and reports a facile route for synthesis of such nanoparticles, using microwave irradiation as a homogenous and powerful source of heating, using ethylene glycol as the solvent and heating medium. For more investigations, besides microwave heating, the obtained solutions were also treated by conventio...

We have previously developed water-based microwave (MW)-assisted peptide synthesis using Fmoc-amino acid nanopaticles. It is an organic solvent-free, environmentally friendly method for peptide synthesis. Here we describe water-based MW-assisted solid-phase synthesis using Boc-amino acid nanoparticles. The microwave irradiation allowed rapid solid-phase reaction of nanoparticle reactants on the...

Glycoscience is an emerging field of science that focuses on the study of the structure, biosynthesis, biology, and evolution of saccharides (sugars). It covers a broad range of subjects including microwave-assisted synthesis as well as sphingolipid synthesis. In this field, knowledge is limited due to the complexity of carbohydrates and their derivatives. Therefore, it is all the more importan...

A new multidisciplinary synthetic approach comprising polymer-support synthesis, microwave-assisted synthesis, and multicomponent condensation facilitates synthesis of triaza-fluorenes library with a set of advantages such as rapid process, simple purification, and structural diversity in one shot. Microwave-assisted multistep synthetic protocol was used to construct the benzimidazole ring on s...
