Abstract:
The inhibition effect of series of thiadiazole derivatives against the corrosion of mild steel in 15 % HCl was studied by weight-loss method and electrochemical measurements. The experiments were performed on steel St3 at 293 K, the exposure time of the samples in solution for weight-loss measurements was 24 h. Potentiodynamic polarization curves were obtained in a typical three electrode cell with the help of electrochemical measuring complex SOLARTRON 1280 C. A scan rate was 1 mV⋅s-1 and a measurement point was taken every 0.2 s. 2-aminothiazole, 5-amino-1,3,4-thiadiazole-2-thiol, 2-amino-1,3,4-thiadiazole, 2-amino-5-(furan-2-yl)- 1,3,4-thiadiazole, 1,3,4-thiadiazole-2-ylamide of acetic acid were studied as potential inhibitors. The maximal inhibition efficiency was obtained at concentration 0.10-0.20 g⋅L−1. The best result was demonstrated by 5-amino-1,3,4-thiadiazole-2-thiol (inhibition effect was more than 90 %). The minimal inhibition effect had 1,3,4-thiadiazole-2-ylamide acetic acid. The corrosion inhibition effect calculated from data of the corrosion current density and from the weight-loss measurements were in sufficiently good agreement. The effective activation energy of the corrosion of St3 increased significantly due the presence of the inhibitors (from 3.3 to 94.8 kJ⋅mol-1). The results point to promising of investigating of series of thiadiazole derivatives and inhibitory compositions based on thiadiazole as potential acid corrosion inhibitors.

Abstract:
Dans la premiere partie, la monofonctionnalisation du 2,5-dimethyl-1,3,4-thiadiazole a pu etre obtenue aisement par formation du monolithien a l'aide du diisopropylamidure de lithium, suivie d'une reaction d'addition aux composes a liaison c=o ou de substitution avec les sels d'iminium et des derives halogenes de structure variee. Cette reaction a conduit a des series organisees de composes thiadiazoliques : alcools secondaires ou tertiaires, cetones, oximes et amines tertiaires. Dans la seconde partie, la realisation dans de bonnes conditions de la difonctionnalisation symetrique du 2,5-dimethyl-1,3,4-thiadiazole s'est revelee plus complexe. Les conditions experimentales optimales ont ete determinees afin d'obtenir des rendements satisfaisants a partir des derives carbonyles et des sels d'iminium. Nous avons ainsi pu preparer des series de composes difonctionnels, analogues aux series precedentes. L'etude de la polyalkylation du 2,5-dimethyl-1,3,4-thiadiazole par polylithiation, puis action des derives halogenes, a permis de determiner le degre maximum de substitution qu'il etait possible d'atteindre : il s'agit de l'hexasubstitution dans le cas de l'iodure de methyle et de la tetrasubstitution symetrique dans les cas du chlorure de trimethylsilyle et du bromure de benzyle. Dans la troisieme partie, en vue d'etablir des comparaisons entre les types structuraux azole-c-c-aryle et azole-n-c-aryle au niveau des proprietes phytosanitaires, nous avons realise la synthese de plusieurs amides n-thiadiazoliques, avec d'excellents rendements. Parmi tous les produits prepares, trente six ont ete testes par la societe novartis en vue de determiner leur activite en tant que fongicides et/ou herbicides. Le 5-methyl-23-methyl-2-(4-morpholino)butyl-1,3,4-thiadiazole s'est montre le compose le plus interessant.

Abstract:
Depuis plus d’un siècle, la chimie hétérocyclique représente l’un des plus vastes domaines de recherche en chimie organique. En particulier, les hétérocycles bicycliques fusionnés à 5 chaînons, contenant à la fois des atomes de soufre et d’azote, présentent, de par leur rareté et leur potentiel biologique, un champ d’intérêt croissant pour les équipes de recherche et développement académiques ou des entreprises pharmaceutiques. Parmi les nombreux composés bicycliques [5-5], notre étude s’est focalisée sur le noyau imidazo[2,1-b][1,3,4]thiadiazole décrit sporadiquement dans la littérature et pour lequel les voies d’accès actuelles ne se limitent qu’à une seule méthode faisant intervenir une étape de cyclisation et des conditions drastiques. Ce verrou entraine inéluctablement une faible diversité fonctionnelle autour de cet hétérocycle, restreignant ainsi les domaines d’applications notamment biologiques. Afin de pallier à cette problématique, nous avons initié une étude de la réactivité de chacune des trois positions fonctionnalisables du bicycle imidazo[2,1-b][1,3,4]thiadiazole, développant ainsi diverses réactions pallado-catalysées (Suzuki-Miyaura, CH-arylation, Buchwald-Hartwig), de substitution nucléophile aromatique et de Pictet-Spengler. L’étude des propriétés biologiques des différents composés synthétisés et hautement valorisables durant ces travaux a abouti à la découverte de deux séries de molécules inhibant sélectivement les kinases DYRK-1A et CLK-1, deux protéines d’intérêt dans le traitement des affections du système nerveux central (neuropathies, Alzheimer…)
For more than a century, heterocyclic chemistry is one of the largest area in organic chemistry research. In particular, because of their rarity and their biological potential, [5-5] fused ring heterocycles containing both sulfur and nitrogen atoms are a large area of interest for both academic and industrial research and development teams. Among these numerous [5-5] bicycles, our study is focused on imidazo[2,1-b][1,3,4]thiadiazole scaffold, which is quite few described in the literature and whose pathways are limited to almost one method involving a cyclisation step and drastic conditions. This lock leads inevitably to low functional diversity around this heterocycle, thus restricting its applications, including biological. In order to overcome this problematic, we then initiated the reactivity study of each three positions of the bicycle imidazo[2,1-b][1,3,4]thiadiazole, developing thereby several palladium couplings (Suzuki-Miyaura, direct arylation, Buchwald-Hartwig), as well as aromatic nucleophilic substitution and Pictet-Spengler reaction. The study of the biological properties of the different compounds synthesized in this work and highly valuable led to the discovery of two series of molecules, inhibiting selectively DYRK-1A and CLK-1, two kinases of interest in the treatment of dysfunction of central nervous system (neuropathies, Alzheimer…)

Abstract:
Die vorliegende Arbeit befasst sich mit der Synthese und der Untersuchung von Struktur-Eigenschaftsbeziehungen neuartiger V-förmiger, formstabiler Mesogene zur Realisierung biaxial nematischer Mesophasen (Nb). Alle synthetisierten Verbindungen besitzen ein formtreues Oligo(phenylenethinylen)-Grundgerüst, an welches laterale Alkyloxyketten und verschiedene terminale Substituenten (z. B. -CN, O(CH2)nCOOEt, Pyridyle) angebunden wurden. Durch dieses spezielle Design erhält man ausschließlich nematische und keine höher geordneten flüssigkristallinen Phasen. Durch den Einsatz verschiedener zentraler heterozyklischer Kernbausteine konnten erfolgreich Öffnungswinkel zwischen 108.9° und 160° realisiert werden. Dabei zeigen Thiadiazolderivate stets enantiotrope Mesophasen, wobei im Hochtemperaturbereich eine uniaxiale Phase mit biaxialen Aggregaten vorliegt. Beim Abkühlen konnte bei etwa 50 °C mittels Polarisationsmikroskopie und dielektrischer Spektroskopie ein Übergang in die Nb-Phase nachgewiesen werden. Die erstmalige Beobachtung eines direkten Übergangs von der isotropen Phase in die Nb-Phase gelang durch den Einsatz von Benzo[1,2-b:4,3-b]dithiophen als Kernbaustein.

The investigation was prepared by the reaction with thiosemicarbazide, carbon disulfide, p-substiuented-benzoic acid in ethanol at refluxed to get 1,3,4-thiadiazole(3、5a~5d). Then 1,3,4-thiadiazole derivatives coupled with N-substiuented-pyridone derivatives(12a~12j) and pyroazolone derivatives(13a~13j). Furthermore, 1,3,4-thiadiazole intermediates were reacted with cyanuric chloride to give a reactive dyes (20), and these dyes condensed with hydrazine hydrate and 4-nitrobenzaldehyde in ethanol to obtain azo-methine dyes (26a~26b)。 Characterization of these dyes was carried out by spectral and elemental analysis. The solvent effect in the visible absorption spectra was also evaluated.

In the first series, the preparation, characterization and mesomorphic properties of palladium chloride and palladium bromide complexes derived from bis-(1,3,4-thiadiazole) derivatives are described. These compounds with a different number of alkoxy side chain exhibited various mesophases, which were studied and investigated by differential scanning calorimeter (DSC), polarized optical microscopy (POM) and powder X-ray diffraction (XRD). The formation of mesophases was found to be sensitive to the number of the alkoxy side chain, carbon length of the side chains, stereo geometry, and the coordination of metal centers. As light emittng materials, the physical properties by UV-Vis spectrophotometer, and photoluminescence (PL) were also studied and discussed. In the second series, a new type of metallomesogenic complexes structurally similar to the first series with a OH group added was prepared ane studied. Theses metal complexes were coordinated in different geometries from the first series. All compounds in the series existing intramolecular hydrogen bond and an ESIPT behavior, were investigated by FT-IR and UV-PL. In addition, in order to better understand the molecular arrangement in columnar mesophases, the molecular volume dilatomery and other parameters were also measured and discussed.
