Abstract:

The synthesis of 7-amino-2-methylquinoline-5-8-dione (17) and 7-amino-3-methylquinoline-5,8-dione (157) are described.7-Amino-3-methylquinoline-5,8-dione (157) was prepared via alkaline hydrolysis of 7-acetamido-3-methylquinoline5,8-dione (149). 7-Acetamido-3-methylquinoline-5,8-dione (149) was prepared via the Diels-Alder reaction of 2-acetamido-6-bromo-1,4-benzoquinone (6) and 2-methyl-2propenal dimethylhydrazone (110).7-Amino-2-methylquinoline-5,8-dione (17) was prepared by the acid hydrolysis of 7-(triphenylphosphineimino)-2methylquinoline-5,8-dione (16). 7-(Triphenylphosphineimino)2-methy

Abstract:

Les ions métalliques ZnII, CuII et FeIII interagissent avec le peptide b-amyloïde (Ab) dans la maladie d'Alzheimer. Ils participent à la précipitation d'A_ et à sa toxicité via la production d'H2O2. Une stratégie thérapeutique consiste à chélater ces ions métalliques par des ligands hétérocycliques reliés de façon covalente afin d'augmenter leur affinité pour ces ions. Parmi eux, la Cyclo-bi-Phen diminue les plaques amyloïdes de souris transgéniques modélisant la maladie d'Alzheimer. Une nouvelle série a été établie à partir du clioquinol, un ligand quinoléine actif in vitro et in vivo. Plus d

Abstract:

Despite the prevalence of supramolecular architectures derived from metal-ligand or hydrogen-bonding interactions, few studies have focused on the simultaneous use of these two strategies to form discrete metal-ligand hydrogen-bonded (MLHB) assemblies. The design, synthesis, and characterization of 2-quinolone based hybrid subunits, 7-DPQ and 5-PYQ, that contain phosphine and pyridyl metal binding sites, respectively, is reported. Both subunits give two-fold symmetric hydrogen-bonded tectons that assemble with metal precursors to give hybrid MLHB structures. Treatment of [Cp*RhCl2]2 with t

L'usage excessif des antibiotiques en médecine humaine et animale pose de graves problèmes environnementaux et de santé publique. L’objectif de cette thèse était d’éliminer deux types d’antibiotiques quinolones pouvant être détectés dans des eaux usées ou effluents hospitaliers. Dans un premier temps, nous avons évalué la réactivité d’oxydes métalliques (fer ou zinc) pour promouvoir des réactions d’oxydation avancée, en présence d’oxydants comme le peroxyde d’hydrogène, le persulfate ou le peroxymonosulfate, et sous irradiation (UVA ou visible).

The subject liquid crystals were prepard in a short two-step reaction. First, 4-alkyloxyphenylmagnesium bromides were added to N-phrnyloxycarbonyl-6-methyl-quinoline,affording a dihydroquinoline, which was then oxidized by o-chloranil. The resulting products,2-(4-alkoxyphenyl)-6-methyl-quinoline, were obtained in good yield(50%~60%). Thermotropic behaviors of these liquid crystals were investigated using differen

Abstract:

A novel, convenient, and high-yielding method has been developed for the preparation of heterocyclic N-oxides. The reaction uses the urea·hydrogen peroxide addition complex as a peroxide source for the in situ generation of trifluoroperacetic acid. The advantages of this method are easy handling of a stable, solid oxidant; high yields and simple removal of excess reagents and by-products.
