Abstract:

By direct coupling 7-azaindole and cyclic imines, such as 3,4-dihydroisoquinoline, 6,7-dihydrothieno[3,2-c]pyridine, 3,4-dihydro-β-carboline, and 4,5-dihydro-3H-benz[c]azepine, new 3-substituted 7-azaindole derivatives have been synthesized. The reaction was extended to 4-azaindoles and 6-azaindoles, as electron-rich aromatic compounds. The lowest reactivity was observed in the case of C-3 substitution of 5-azaindole. In this case, the aza-Friedel-Crafts reaction took place by using 10 mol % of p-toluenesulfonic acid (p-TSA) as the catalyst. The role of the acid catalyst can be explained by th

Abstract:

After geometry optimization, the electron spectra of indole and four azaindoles are calculated by density functional theory. Available experimental photoemission and excitation data for indole and 7-azaindole are used to compare with the theoretical values. The results for the other azaindoles are presented as predictions to help the interpretation of experimental spectra when they become available.

Abstract:

The reaction of NbCl5 and TaCl5 with 7-azaindole (Haza) at room temperature in benzene or dichloromethane yielded MCl5(Haza) addition compounds. Under more severe conditions, the same compound was obtained with TaCl5. For NbCl5, some reduction to Nb(IV) was observed and NbCl5(Haza), NbCl4(Haza)2, and the (H2aza)+ ion were identified in the reaction mixture by infrared spectroscopy. Oxidative coupling of two azaindole units via N7—C6 also took place during the reaction, since the 7-(azaindol-6-yl)azaindolium cation was found as counter-ion in the crystal structures of two complex salts.

Abstract:

Five protocols were first compared for the copper-catalyzed C-N bond formation between 7-azaindole and aryl/heteroaryl iodides/bromides. The 1-arylated 7-azaindoles thus obtained were subjected to deprotometalation-iodolysis sequences using lithium 2,2,6,6-tetramethylpiperidide as the base and the corresponding zinc diamide as an in situ trap. The reactivity of the substrate was discussed in light of the calculated atomic charges and the pKa values. The behavior of the 1-arylated 7-azaindoles in direct iodination was then studied, and the results explained by considering the HOMO orbital coeff

Alors que la majorité des architectures décrites sont homométalliques, l'obtention de leurs analogues hétérométalliques représente un défi synthétique. En effet, une approche «one-pot)), par principe, peut mener à un mélange statistique de composés homo- et hétérométalliques.

Abstract:

DYRK1A is a dual-specificity protein kinase that catalyses not only autophosphorylation on its tyrosine residue but the phosphorylation of serine and threonine residues in its substrates. DYRK1A has been shown to be important for phosphorylation of tau protein and has also been identified as a Down syndrome candidate gene. DYRK1A overexpression has also been found in cancer cells, particularly in glioblastoma, which represents 15% of brain tumours. The increased phosphorylation of sprouty2 mediated by DYRK1A blocks the EGFR degradation as a result of overexpression of EGFR in the cell surface,

Abstract:

7-Azaindole (7AI) is one of a class of molecules that exhibit dual fluorescence as a result of excited-state tautomer formation. The tautomer is reached through a proton transfer from the initially excited "normal" form, the only form present in the ground electronic state. When isolated (in the gas phase or in non-hydroxylic solvents) 7AI does not tautomerize at an observable rate. However, in non-polar solvents, 7-azaindole forms dimers which enable the excited-state tautomerization to occur via a double proton transfer mechanism. Tautomerization in 7AI dimers has been studied for quite some
