Повний текст джерелаLa catálisis homogénea de oro(I) es una poderosa herramienta para la construcción de complejidad molecular en condiciones suaves mediante la activación selectiva de enlaces múltiples C-C. Nuestro grupo ha desarrollado una serie de reacciones de alquinos con alquenos catalizadas por oro(I), tanto de forma intramolecular como intermolecular. Estas reacciones comienzan con el ataque nucleofílico del doble enlace al alquino para formar un intermedio tipo ciclopropil carbeno de oro(I), que evoluciona para dar lugar a diferentes productos. En esta Tesis Doctoral se describen una serie de nuevas reacciones intermoleculares entre alquenos y alquinos sustituidos con heteroátomos catalizadas por oro(I). Además, se presentan los estudios mecanísticos correspondientes, realizados mediante experimentos y cálculos DFT. En las reacciones entre bromoalquinos y alquenos catalizadas por oro(I), inicialmente se genera un 1-bromo ciclopropil carbeno de oro(I) que evoluciona a través de un catión bromonio cíclico para formar un vinilideno de oro(I) o un catión vinilidilarenio estabilizado por oro. Los cálculos DFT demuestran que estos dos intermedios son confórmeros de la misma especie pero tienen diferente reactividad. Los vinilidenos de oro(I) pueden participar en reacciones de activacion C-H o de hidroarilación, mientras que los cationes vinilidilarenio participan en transposiciones 1,2 del areno para formar enlaces triples.
Homogeneous gold(I) catalysis is a powerful tool for the construction of molecular complexity under mild conditions by mean of the selective activation of C-C multiple bonds. Our group developed a series of gold(I)-catalyzed reactions of alkynes with alkenes both in intramolecular and intermolecular settings. These reactions start with the nucleophilic attack of the double bond on the alkyne to form a cyclopropyl gold(I) carbene intermediate that than rearranges into a variety of products. In this Doctoral Thesis we present a series of new gold(I)-catalyzed intermolecular reactions of heteroatom-substituted alkynes with alkenes and the mechanistic investigation we performed by means of experimental work and DFT calculations. In the gold(I) catalyzed reactions of bromoalkynes with alkenes, the 1-bromo-cyclopropyl gold(I) carbene initially formed rearranges into gold(I) vinylidenes and vinylidenephenonium gold(I) cations passing through a cyclic bromonium intermediate. DFT calculations demonstrated that these two reactive intermediates are conformers of the same species but have different reactivity. On one side gold(I)-vinylidenes can undergo hydroarylation or C-H insertion, while vinylidenephenonium gold(I) cations easily undergo 1,2-aryl shift forming a triple bond. Moreover, we found that terminal alkynyl ethers are undergoing efficiently [2+2] cycloaddition with alkenes to form cyclobutene derivatives that can be easily transformed into the corresponding cyclobutanones.

Повний текст джерелаtherefore, many different approaches to generate this skeleton have been developed so far. In this study, our prior aim was to develop a new synthetic methodology for the formation of pyrrolo[1,2-a]pyrazine moiety. In the first part of this focus, the starting compound, methyl 2-(2-methoxy-2-oxoethyl)-1-(prop-2-yn-1-yl)-1H-pyrrole-3-carboxylate was successfully synthesized, then the conversion of the ester group at the lower arm to the amine group was carried out. Heteroatom cyclization catalyzed by CuI afforded the desired substituted pyrrolo[1,2-a]pyrazine structure. In the second part, it was aimed to synthesize new compounds with unusual structures which are not described in the literature
namely, as pyrrolo[1,2-a]pyrazine N-oxide. In this direction, first pyrrole was submitted to Vilsmeier-Haack reaction to attach a formyl group at C-2. Substitution reaction then effectively gave 1-(prop-2-yn-1-yl)-1H-pyrrole-2-carbaldehyde, which was a key molecule to synthesize the aldoxime. AuCl3 catalyzed cyclization of the corresponding oxime afforded pyrrolo[1,2-a]pyrazine N-oxide. In the next step, Sonogashira coupling reactions were carried out to obtain terminal alkynes (RC&equiv
CR'
) starting from 1-(prop-2-yn-1-yl)-1H-pyrrole-2-carbaldehyde. The aim of this part was to study the effect of aryl groups to the activated alkyl functional group by a metal catalyst. In this case, unexpected oxime-oxime transformation was observed, which is unprecedented in the literature

Повний текст джерелаLe Développement d'Approches en Un Pot, Catalysées par un Métal de Transition pour la Synthèse d'-Acides Aminés, Pyrroles et d'Amides -SubstituésL'objectif de cette recherche était de dévolopper une nouvelle méthode en un pot pour former des produits biologiquement importants contenant un azote, tels que les pyrroles, les dérivés d'acides aminés et les amines/amides α-substitués. Ces produits sont tous générés à partir de produits de départ facilement disponible, tels que les imines, les chlorures d'acides, les alcynes et/ou le monoxide de carbone, et souvent via la catalyse par un métal de transition.Le chapitre 2 de cette thèse décrit comment les α-phenoxyamides peuvent être utilisés dans les carbonylations catalysées par le palladium pour former des dérivés d'α-acides aminés, au lieu de la synthèse, précédemment reportée, avec des imines et des chlorures d'acides. Ces substrats sont similaires aux sels d'iminiums N-acylés formés in situ mais ils ont l'avantage d'être plus stable, et en présence d'un complexe de palladium(0) (Pd2dba3) et d'un acide de Lewis, ils peuvent subir une activation de liaison carbone-oxygène pour former des palladacyles. Le couplage de cette addition oxydante avec la carbonylation fournit un voie douce et en une étape pour préparer des dérivés d'α-acides aminés avec de hauts rendements.Dans le chapitre 3, nous montrons que, sans l'assistance d'acides de Lewis, les α-(3-pyridyloxy)amides peuvent directement subir une addition oxydante avec un catalyseur de palladium et peuvent être employés dans la carbonylation catalysée par le palladium pour former des dérivés d'α-acides aminés. Cette réaction exige aucuns co-catalyseurs acides ou basiques, et elle tolère de nombreux substituents sensibles. De plus, cette réaction de carbonylation peut se coupler à la cycloaddition avec un alcyne pour former des pyrroles en une é
