The discovery and implementation of new materials in sample preparation have a significant impact on the development of new analytical methods and often on the instrumentation used in chemical analysis. In recent years, nanostructured materials of different chemical composition, such as nanoparticles, nanowires or nanotubes have received increasing attention. Their introduction in almost every stage of chemical analysis Read More

Native glycosidic bonds in carbohydrates, are sensitive to the presence of enzymes. Thus, design of small molecule mimics (glycomimetics) is an active area of research. This review will focus on the development of a new class of glycomimetics: anomeric and N-glycosyl sulfonamides. These novel compounds have been demonstrated to be enzyme inhibitors or antiproliferative agents.

Due to its particular properties the use of ionic liquids in organic transformations is maturing. Immobilized ionic liquids, supported in different substrates or used as functional support, have found important applications in the last decade. In this review, a critical overview of the applications of immobilized ionic liquids in organic transformations as catalysts or to carry reagents or nanoparticles will be presented. Special releva Read More

Theoretical computations were performed on the 1,3-dipolar cycloaddition reactions of pyridinium-3-olates and pyrazinium-3- olates with methyl methacrylate employing density functional theory at the B3LYP/6-31G(d) level in the gas phase and in THF. The two possible regioisomeric pathways, forming 6-esters and 7-esters, along with the two stereoisomeric channels, endo and exo, have been considered. Thermodyn Read More

By facile condensation of aromatic amines 4-aminobenzoic acid, 2-amino-4, 6-dimethylpyrimidine, 3-aminopyridine, 4- bromobenzenamine and 4-methylbenzenamine with glyoxal and formaldehyde, catalyzed by acid or base under one or two step reaction sequence, five novel (±) trans-4,5-dihydroxy-1,3-diarylimidazolidines (DHDAIs) were prepared and characterized by X-ray single crystal analysis, NMR, IR and elemental analysis.
