Abstract:
Formylated chlorothieno[2,3-b]pyridine derivatives were synthesized by reaction between N-protected 3-acetyl-2-aminothiophenes and Vilsmeier–Haack reagent under classical conditions. These products were not accessible without N-protection of the starting materials or by reaction between the reagent and 4-chlorothieno[2,3-b]pyridine under any conditions. The conditions of the reaction could be altered to produce unformylated derivatives in better yields than reaction with unprotected aminothiophene.

Abstract:
Potentiometric measurements carried out in a 50-50 (v/v) H2O-Me2SO mixture together with 1H and 13C NMR studies carried out in pure Me2SO-d6 reveal that 3-aminothiophene (4a), 3-N-(methylamino)thiophene (4b), and 3-N,N-dimethylaminothiophene (4c) undergo protonation exclusively at the amino groups in dilute acid solutions. The pKa values of 4a, 4b, and 4c are equal to 3.38, 3.65, and 3.53, respectively, at 25°C, comparing well with those for related anilines in the same aqueous Me2SO mixtures. However, despite this similarity of the nitrogen basicities, compounds 4a, 4b, and 4c are found to be

Abstract:
Un intérêt grandissant pour le système thiéno[2,3-b] pyridine est apparu ces trois dernières décennies. De nombreux chercheurs ont présentés des composés basés sur ce système comme traitement possible de l'anxiété et de la dépression, comme bactéricide, contre l'inflammation et la leishmania, la malaria et les maladies auto-immunes. Les ortho-amino acyl thiophènes sont des produits de départ possible pour synthétiser ces motifs. L'accès à ce type de composés sera la première étape de ce travail.

Bromination and ipso-iododesilylation of these heterocyclic scaffolds provided synthetic methods to efficiently generate key intermediates, allowing for great versatility. Bisphosphonic acid derivatives of thieno[2,3-d]pyrimidine and benzothiazole scaffolds, with favourable physicochemical properties, were evaluated for their ability to inhibit isoprenoid biosynthesis and pote
