Der volle Inhalt der QuelleThis thesis mainly deals with various aspects of xanthate radical chemistry. The first chapter is a general introduction to radical chemistry and provides an overview of the xanthate radical chemistry. The next chapter presents a new methodology for the synthesis of polycyclic aromatic compounds from strained epoxy-olefins. The third chapter describes the total synthesis of the purported structure of flossonol and of one of its isomers and concludes with the resolution of the structure of the natural product. The next section presents the study of different strategies for the synthesis of pseudoptéroxazole. In this work, a method of net contra-thermodynamic isomerization of carbon- carbon trisubstituted endocyclic double bonds has been developed and is the subject of the fifth chapter. The sixth part of the manuscript deals with an attempt to synthesize the structure of eudesmanes and finally , the seventh chapter presents a methodology for the synthesis of benzene derivatives through a 1-5 acyl transfer starting from a 3-methylene-1,4-cyclohexadiene

Der volle Inhalt der QuelleThe development of novel reactions in chemistry, as well as the total synthesis of natural products are very important fields, in order to synthetize new molecules that possess interesting biological activity. The strategies developped should be simple, efficient, easily transposed on large scale and environmentally friendly. In the first part of this thesis, we set up an original methodology to synthetise biaryl structures by a non catalyzed coupling reaction of an aryllithium and a haloarene. The reactants are cheap, commercially available, and the reaction could easily be transposed on large scale. During this study, we evidenced a new direct nucleophilic aromatic substitution pathway for this coupling reaction. In the second part, we developped a new thiolating agent of aromatic compounds by a Friedel-Crafts type reaction with an activated sulfoxyde. This methodology has been extended to the solid phase for the synthesis of a polystyrene thiol resin. In the last part, we studied an original synthesis, that gives easily acces in a few steps to (2S,3R,4S)-4-hydroxy-isoleucine, a non natural aminoacid that possess very interesting antidiabetic activity. Two strategies were involved. Firstly, we studied an enantioselective epoxyde opening reaction by an anion derived from several amino-acids. Secondly, we considered an asymetric hydrogenation procedure of an achiral precursor of 4-hydroxy-isoleucine. Eventually, we were interested in the synthesis of a novel diamine that could easily be used as a ligand for asymmetric catalysis

Der volle Inhalt der QuelleThe primary objective of our doctoral research was centered on the use of aryl halides as electrophiles for nucleophilic aromatic substitution (SNAr). First, we tried to create C(aryl)−heteroatom bonds by reacting heteroatom nucleophiles with aryl halides substituted by electron-withdrawing groups. The results of this study were compared with inconsistencies found in the literature and show that the expected order of reactivity of aryl halides is not always observed. A beneficial effect was observed by adding 2,2,6,6-tetramethylheptane-3,5-dione to the reaction of phenols and aryl halides substituted by electron-donating groups in what is the first method allowing the synthesis of diarylethers without added metal catalysts by this pathway. Second, we developed a general α-arylation reaction of aryl ketones with aryl halides under mild reaction conditions. Use of KOt-Bu, an inorganic base capable of single-electron transfer, and DMF as additive enables the synthesis of α-arylketones in excellent yields. This method was applied to the synthesis of fused heterocycles and (Z) tamoxifen, molecules possessing biological activity. A mechanistic study showed that the carbamoyl anion of DMF is involved in a single-electron transfer reaction with aryl halides as the key step of the mechanism. We next applied this method to the nucleophilic vinylic substitution of β-halogenostyrenes. While literature precedents suggest ionic mechanisms for reactions involving these substrates, we obtained experimental evidence suggesting a radical mechanism. Third, we tried to develop the first protocol enabling the copper-catalyzed synthesis of unsymmetrical biaryls starting from aryl halides and triarylbismuthanes(III). Although many bidentate and tetradentated ligands were tested, further optimization is required in order to develop a general method, as only low yields are obtained. Globally, we have contributed to the determination of the experimental frontier between SNAr and metallic catalysis, to the α-functionnalization of aryl ketones and to the synthesis of biaryls through copper-catalyzed cross-coupling reactions of triarylbismuths
