Chemo-enzymatic synthesis as an efficient and environmental friendly strategy to access furanosidic compounds. Alpha-L-arabinofuranosidase from Clostridium thermocellum (Araf51), a thermostable glycosidase, is able to use arabinofuranosyl-donors to catalyse transglycosylation reactions with various aliphatic alcohols to give the corresponding glycoconjugates. Thanks to random mutagenesis method involving the development of an efficient screening, five mutants were obtained. In comparison to the wild type enzyme, they improve the reaction time, the conversion rate and the specificity to the alkyl furanoside formation. Many efforts have focused on the extraction and conversion of renewable biomass as biofuels or biocompounds but have neglected the pentose polymers from hemicellulose which represent 30 % of the total biomass. Hydrolysis of sustainable polymers as arabinan or arabinoxylan by the araf51 was studied. To enhance the hydrolysis rate, mutants were selected by a screening based on the conditions of the transglycosylation reaction performed to produce methyl-alpha-L-arabinofuranoside by the Araf51. We also demonstrate that a cyclodextrin glycosyltransferase, CGTase from Thermoanaerobacterium sp. Was able to recognize and glucosylate alkyl and para-nitrophenyl furanosides using beta-cyclodextrin as substrate with efficiency. The compounds were identified and presented only one interesting regioisomery. These compounds are good targets as amphiphilic molecules, building block or immunostimulating and anti-parasitic drug

This Ph-D work in collaboration with Laboratoires Pierre Fabre has lead to the developpment of new synthetic routes to biologically active coumpounds. In chapter 1, we have synthetised Mequitazine by a new route. Key step is a palladium-catalysed allylic substitution on a new allylic substrate. Racemic Mequitazine is obtained by hydrogenation in the last step, but this route could lead to biologically active Mequitazine enantiomer by the mean of an asymmetric hydrogenation catalyst. Two new ways for the synthesis of Rhein has been developped in chapter 2. They are both based on ortho-metallation reaction. The first route has been optimised so that it can be used industrially, while the second one, by changing the electrophile, leads to Rhein in only three steps. Last step’s Friedel Crafts’acylation selectivity has been improved by detailed study of Hayashi rearrangement in molten salt. In a third chapter, a new method for converting -fluorocyanhydrines into aldehydes has been studied

The research projects that I have been involved during my PhD are all focused on the development of new processes for the synthesis of nitrogen heterocycles based on a unified approach relying on the use of intramolecular carbometallation reactions from ynamides. These unique molecules, whose chemistry has been under intense investigation during the last decade, notably for the inclusion of nitrogen-based functional groups into organic molecules, are emerging as useful and versatile building blocks in organic synthesis. Capitalizing on their unique reactivity, we have been able to design new processes in heterocyclic chemistry based on various carbometallation reactions starting from conveniently substituted ynamides. Indeed, we developed new routes to dihydropyridines, pyridines and indoles by intramolecular carbolithiation or carbocupration of ynamides. These new reactions allow for a straightforward and original entry to these various heterocyclic systems, which could be highlighted by a formal synthesis of a bioactive compound: Sarizotan. All together, this work should contribute to further expand the synthetic utility of ynamides as well as intramolecular carbometallation reactions in organic synthesis

The aim of this work is to develop new synthetic methods for preparation of reactive nucleophilic species by activation of polyhalomethyl compounds. The latter species would react with various electrophilic compounds to produce small rings. An electrochemical process involving an iron/copper complex catalytic system and a simple Barbier reaction involving magnesium in DMF were used to prepare cyclopropanes, oxiranes and aziridines from respectively alpha, beta-unsaturated ketones or esters, nonconjugated aldehydes or ketones, and imines. These two simple and complementaiy new processes provide good yields in small rings, and moreover, they must be regarded as interesting alternatives to most common syntheses which use pollutant compounds or require very complex procedures. The 2-acyl-1,1-diphenylcyclopropanes thus obtained lead, through acid-catalysed ring-opening, to either substituted naphtalenes or beta-benzhydryl-alpha, beta-cycloalkenones

This manuscript describes several works that take profit of classical organic transformations to develop novel synthetic methodologies. The strategies developed are environmentally friendly and economically relevant. In the first part, we made use of an alkylsodium base in situ generated from chlorooctane and sodium in the ortho- or a-metalation of (hetero)aromatic compounds. The reagents needed are stable, cheap and the conditions used are especially well adapted to an industrial usage. Combination of the aromatic substrate affinity for Na+ associated to proton abstraction kinetics allowed us to propose an original mechanism that fully explains our experimental results. In the second part, we tried to synthesize catechin, a natural flavonoid frequently encountered in the plant kingdom. Our strategy was devised as far as possible in aqueous solvents as free polyphenolic compounds are water soluble, and was focused on phloroglucinol alkylation with different alkylhalides. In each case, excellent mono-C-alkylation selectivity was obtained. Finally, we developed an alternative strategy to transform secondary nitro compounds into ketones by means of nitrosating species auto-catalytically generated under neutral conditions from NaNO2. In annex, we also report our attempts to fabricate a photonic band-gap material from functionalized silica nano-beads
