Abstract:

The design of partially reduced 1,1'-bisisoquinoline derivatives was investigated with the aim of controlling the conformation about the C1-C1' axis. This would produce ligands with unusual but predictable ligand binding properties, particularly cooperativity. The introduction of ??-aminoalkyl, ??-azidoalkyl, ??-alkynyl and ??-alkenyl groups onto the nitrogens of the reduced bisisoquinoline core was conducted with the intention of broadening the scope of the ligand.

Abstract:

The last decade has been marked by a large increase of demand for green chemistry processes. Consequently, chemists have focused their efforts on the development of more direct routes toward different classes of targets. In that regard catalysis has played a crucial role at enabling key bond formations that were otherwise inaccessible or very energy and resources consuming. The central theme of this body of work concerns the formation of C–N bonds, either through transition metal catalysis or organocatalysis. These structural units being highly recurrent in biologically active molecules, the e

Abstract:

Pyrroloisoquinoline (n = 1) and the pyridoisoquinoline (n = 2) ring systems (2) are found to be the major structural motif of the Erythrina and the protoberberine group of alkaloids, respectively. We have recognised that suitable bicyclic lactams (1) could act as precursors, in an intramolecular N-acyliminium ion-mediated cyclisation, resulting in a stereoselective approach to the core of the Erythrina and protoberberine ring systems. [Illustration omitted.] Access to the tetracyclic core of the Erythrina alkaloids (3) through the application of N-acyliminium ion chemistry is well established

The cortistatins are a recently identified class of marine natural products that were found to exhibit potent and selective inhibition of human umbilical vein endothelial cells (HUVECs), making them promising leads for the development of anti-angiogenic drugs. In our synthesis, we envisioned that natural cortistatins and unnatural analogs could be prepared by late-stage introduction of isoquinolines to 17-keto precursors, and that these differentially substituted precursors could all be derived from a common key intermediate 112.

Abstract:

The decomposition mechanisms of various coal constituents undergoing pyrolysis are of great concern in environmental circles (especially those coal constituents containing nitrogen). Most methods of burning coal that are efficient involve doing so at high temperatures. This invariably results in a large portion of non-combusting coal being heated to high temperatures also causing pyrolysis of the original coal constituents. The end result of such pyrolysis is the production of a number of noxious gaseous products. If we are to design methods of reducing the amount of toxins that are produced f

Abstract:

This study involves a morphological and histological investigation of normal mouse tail skin and its response to crude coal tar and isoquinoline (a major constituent of coal tar). Mouse tail skin is unusual in that it undergoes both parakeratotic and orthokeratotic keratinization in adjacent sites. The former develops without a granular layer and resembles psoriasis, while the latter, with a granular layer, resembles normal human skin. Based on this property, mouse tail skin has frequently been used as a model for psoriasis but in spite of this, an integrated, detailed picture of its structure

Abstract:

Boronic acids play an important role in the design and synthesis of chemosensors for carbohydrates due to their ability to reversibly bind with diol-containing compounds. Along this line, the availability of boronic acids that change fluorescence upon sugar binding is critical to a successful sensor design effort. Here, two boronic acids that show strong fluorescent intensity changes upon sugar binding are reported: isoquinoline-7-boronic acid (7-IQBA) and phenoxathiin-4-boronic acid (4-POBA).

Notre travail est consacre a l'etude de reactions par transfert monoelectronique en serie 5-nitroisoquinoleine. Nous avons dans un premier temps synthetise la 1-chloromethyl 5-nitroisoquinoleine dont l'etude de la reaction avec l'anion du 2-nitropropane a permis de conclure qu'elle se deroulait selon un mecanisme de substitution radicalaire nucleophile unimoleculaire (srn1). Cette reaction a ensuite pu etre generalisee a divers anions nitronate aliphatiques, cycliques et heterocycliques. Pour completer cette etude, la synthese de la 1-dichloromethyl 5-nitroisoquinoleine a ete realisee. L'etude

Abstract:

Nous avons développé une nouvelle approche via la catalyse duale permettant une activation orthogonale de chacun des deux partenaires organométalliques de couplage Pd/Cu afin de réaliser les réactions dans des conditions douces. Nous avons ainsi étudié la réaction d'α-allylation asymétrique de nitrile tertiaire en tirant profit d'une part du potentiel synthétique des céténimines N-métallées (M = Si, Cu) en tant que nucléophiles et d'autre part, de complexes α-allyl chiraux de palladium, en tant que partenaires électrophiles. Les céténimines N-métallés sont douées d'une chiralité planaire intri

Abstract:

L'Urotensine II est un neuropeptide cyclique, initialement isolé chez les poissons téléostéens. Il est constitué par un enchaînement de 11 acides aminés avec une partie C-terminale hexacyclique, responsable de l'activité biologique. Ce système Urotensine II / UT est localisé dans différents tissus cardiovasculaires humains. Des effets puissants (vasoconstriction, prolifération vasculaire. . . ) ont été rapportés dans diverses espèces ainsi que chez l'Homme, suggérant la participation possible du système urotensinergique dans la physiopathologie cardiovasculaire.

Abstract:

Plusieurs séries de dérivés quinoléiques, isoquinoléiques et néoflavonoiques ont été préparées via une réaction clé de couplage de Suzuki, ou par cyclisation intramoléculaire de type Bischler-Napieralski. Des études de prolifération cellulaire ont mis en évidence des activités remarquables pour les composés de type 4-arylquinoléique et 4-indolylcoumarinique. Cette activité antiproliférative a été corrélée à une activité inhibitrice de l'assemblage de la tubuline. La nature et la position des substituants sur le cycle A n'influencent que très finement cette activité. Dans la série des dérivés n

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior<br>In the first part of this work, a series of selenophenes and tellurophenes were prepared starting from of (Z)-chalcogenoenynes, by employing FeCl3 diorganyl dichalcogenide-mediated intramolecular cyclization. In general, the cyclic products were obtained in moderate to good yields. In order to evaluate the versatility of the obtained 3-chalcogen selenophene derivatives, we tested the reactivity of these compounds toward halogenation and Li/Se exchange reactions. In this way, the reaction of 2,5-diphenil-3-(fenilselene)-selenofene w

Cette thèse est divisée en cinq parties. La première partie traite de la chimie des ions iminiums. Après une brève introduction sur leur découverte, sont présentées leurs préparations et leurs applications dans divers champs de la chimie, en particulier dans la synthèse de produits naturels. En suite nous traiterons des ions N-acyl iminiums, en évoquant les mécanismes de leur formation, les diverses applications et leurs particularités. La première partie se termine par la présentation des différentes voies d'accès à des structures du type isoindoquinolinonique obtenues notamment par formation
