Translation of photophysical properties of fluorescent sensors from solution to solid-gas environments functionalized surfaces constitutes a challenge in chemistry. In this work, we report on the chemical synthesis, barium capture...

Dehydration of alcohols in the presence of copper(II) sulfate has been analyzed computationally. Density functional theory (DFT) calculations on selected alcohols indicate that this reaction can take place two possible...

In general, electrocyclizations follow the Woodward-Hoffmann's rules of conservation of orbital symmetry. These rules have been extensively verified in low-order processes, both in thermal and photochemical reactions, up to eight...

The (3+2) cycloaddition between azomethine ylides and alkenes is an efficient, convergent and stereocontrolled method for the synthesis of unnatural pyrrolidine and proline scaffolds. In this review, the application of...

The organocatalytic properties of unnatural α-amino acids are reviewed. Post-translational derivatives of natural α-amino acids include 4-hydroxy-l-proline and 4-amino-l-proline scaffolds, and also proline homologues. The activity of synthetic unnatural α-amino...

The N-demethylation reactions of N,N,N-trimethylpropan-1-ammonium and N,N-dimethyl- and N-methylpropan-1-aminium cations in the presence of [(AcO) (imidazole) (H O)Fe=O] complex have been studied by density functional theory. These transformations are suitable...

The outcome of the cycloaddition between activated ketenes and alpha,beta-unsaturated imines has been investigated both experimentally and theoretically. Our results indicate that activated monosubstituted ketenes yield exclusively [2 + 2]...
