Abstract:

Derivatives based on pyridine-2-6- and furan-2,5-dicarboxamide scaffolds reveal numerous chemical properties and biological activities. This fact makes them an exciting research topic in supramolecular and coordination chemistry and in discovering new pharmacologically-active compounds. This work aimed to obtain a series of symmetrical pyridine-2-6- and furan-2,5-dicarboxamides through a condensation reaction of the appropriate acyl chlorides and aromatic amides. Successful syntheses were confirmed with NMR spectroscopy. We solved their crystal structures for seven compounds; two pyridine and

The present findings led us to conclude that the proposed model is stereochemically stable. The overall PROCHECK G factor for the homology-mod

Abstract:

Functionalized cyclohexanones are multifunctional highly reactive available substrates. They are convenient for the synthesis of new compounds, including practically significant ones. The presence of a 1,3-dicarbonyl fragment in their composition makes it possible to obtain various heterocyclic systems in reactions with binucleophilic reagents: indazoles, benzisoxazoles, and diazepines. The interaction of cyclohexanones functionalized with acetyl or alkoxycarbonyl substituents with hydroxylamine was previously studied. It was shown that, depending on the nature of the substituents, the reactio

Abstract:

We have synthesized and examined several complexes of lanthanides with diamides of 2,2′-bipyridyl-6,6′-dicarboxylic acid bearing various hetaryl-based side chains for the elucidation of the effect of the heterocycle on the structure and properties of the ligands. The multigram scale methods for the preparation of various N-alkyl-hetaryls and their diamides were developed. The solid state structure of 6-methyl-2-pyridylamide of 2,2′-bipyridyl-6,6′-dicarboxylic acid possesses a flat structure where the conformation is completely different from that previously observed for N-alkylated 2,2′-bipyri

Abstract A benzene-1,3-dicarboxamide derivative bearing six (S)-citronellyl ((S)-3,7-dimethyl-6-octen-1-yl) groups forms columnar molecular aggregates with a helical groove in the liquid crystal phase, as confirmed by XRD analyses. When cooled from the isotropic state without an external field, the liquid crystal exhibits spontaneous polarization, which is further enhanced under an applied field. These properties were compared with those of a benzene-1,3-dicarboxamide derivative bearing six racemic citronellyl groups and a benzene-1,3,5-tricarboxamide derivative bearing nine (S)-citronellyl gr
