Full textGalanthamine, an inhibitor of AChE is currently used in many countries for the palliative treatment of Alzheimer's disease. The structure activity of bisligands have been realized in our laboratory. These compounds are more active than galanthamine. We proposed to add an anchoring point in the galanthamine scaffold, since such molecules have beenshoxn to interact with both peripheral and catalytic sites of AChE. Within the framework of this thesis, we were interested in the total synthesis of a novel anchored analogue, azagalanthamine. The retrosynthetic approach to azagalanthamine is based on the total synthesis of galanthamine previously developed in our laboratory. This strategy allowed the synthesis of different intermediates which were engaged in a Heck intramolecular reaction. Unfortunately, the desired compounds were not obtained and the strategy was abandoned. On the other hand, we were also interested in the synthesis of Aspidosperma alkaloids for which we used the same strategy. We thus realized the synthesis of many Aspidosperma alkaloids, and their analogues, in eight steps : an amidification, a intramolecular Heck reaction, an oxidation as well as a rearrangement of the spirodienone intermediate. Furthermore, we have realized the synthesis of the Büchi ketone, and its analogues, via two different methodologies, allowing access to numerous natural products, such as strychnine, vindoline, aspidospermine and tubifoline, by formal synthesis

Full textWithin the framework of this thesis, we were interested in the total synthesis of crinine-type alkaloids, belonging to Amaryllideceae plants. Our strategy is based on the formation of seven membered ring and on the simultanous creation of critical quaternary carbon by intramolecular Heck reaction. First, oxocrinine and oxomaritidine have been synthetised in seven steps in, respectively, 22. 1% and 14. 8% overallyield. Secondly, maritidine, crinine, its methyl ether, the buphanisine have been obtained, in two steps, by diastereoselective enone reduction, followed by SN2 alcohol inversion or by Mitsunobu reaction. The flexinine and augustine syntheses were considered in different ways to get, finally, the epoxy-alcohol with the correct stereochemistry. Unfortunately, the first attempts of alcohol inversion failed, our synthetical target was not obtained. Finally, dienone-phenol rearrangement of the synthetised spirodienone intermediates led to the bridged biaryl compounds, buflavine analogs

Full textThe scientific project involved the development of new palladium catalyzed domino and multi-components reaction for heterocycles synthesis. First we have described a new synthesis of physostigmine which relies on a domino Heck / cyanation reaction key step. An asymmetric version of this reaction has also been developed. In a second part, we have developed a synthesis of 3-(diarylmethylene)oxindoles by a carbopalladation / CH activation / arylation domino process from easily accessible products. Then, with the success of this reaction, two multi-component reactions have been devised. The first one combines a Sonogashira reaction with the carbopalladation / CH fonctionalisation, the second one combines a alladium catalysed amidation reaction with the same domino reaction. During the development of the last domino sequence, we have uncovered a new way to synthesize 6-aryluracil: the synthesis involved a simple dimerisation reaction of 3-arylpropynamide. In the last part, we have carried out preliminary studies to develop a new dihydropyrrole multi-component synthesis using the reactivityof isonitrile and allyl

Full textThis thesis describes Pd-catalyzed dehydrogenative Heck reactions of heteroarenes that could be derived from the biomass with electron-rich alkenes such as styrenes. The first chapter presents a new methodology enabling cross coupling dehydrogenative Heck Reactions of furans and thiophenes with styrenes under Mild conditions and discusses the Influence of the oxidizing agent on the reaction rate. The second chapter focuses on ESI-MS studies of the dehydrogenative Heck reactions of furans with acrylates using benzoquinone as reoxidant and DMSO as solvent. The presentation of a new methodology for aerobic dehydrogenative Heck reactions of heterocycles with styrenes and the explanation about the negative effect of metallic co-oxidants represent the third chapter

Full textThe work is focused on sustainable chemistry, following three principles of green chemistry: catalysis, safe solvents and prevention of wastes. Recyclable palladium nanoparticles,stabilized by ammonium salts, have been used for the chemoselective hydrogenation of alkenes and the hydrogenolysis of benzylic epoxides in water. The mechanism of alkoxyhydroxylation of allylphenols in aqueous medium has been studied and the different steps of this domino reaction have been proposed. The study of coupling of allylbenzene and 2-methylfuran through C-H activation has shown a competition between the formation of difurylalkanes and furylakenes. The synthesis of difurylalkanes has been developped with various alkenes and the mechanism study has led to propose a catalytic cycle, from which four intermediates have been determined by ESI-MS anaysis. Finally, a preliminary study of allylic oxidation of terminal alkenes has been performed

Full textThe aim of this work was to evaluate the catalytic potential in homogeneous catalysis of a tetraphosphine ligand : the cis-cis-cis-1,2,3,4-tetrakis-diphenylphosphinomethyl)cyclopentane or Tedicyp. We have explored the potentiel of this catalyst by investigation of well known palladium-catalyzed Heck reaction. So, we have realised several Heck reactions with different alkenes such as vinylsilanes, 1,1 and 1,2 disubstituted enolethers, vinylsulfars and heterocycles like faranes and thiophenes derivatives. For all the reactions tested, the complex gave very good results, in terms of substrate / catalyst ratio, compared to the traditional complexes. Furthermore, it seems to be more stable and less sensitive to temperature and poisoning
