Texto completoThe extension of the chemical molecular space accessible from plant biomass by soft and clean methods is a timely topic that stimulates the scientific community in order to develop biobased products with low environmental impact and to widen the field of biomass exploitation. The functionalization of cellulose, the most abundant polysaccharide on the planet, and/or cello-oligosaccharides as described in this thesis is part of this approach. Our objective was to develop a chemo-enzymatic method involving the action of a mediator-assisted laccase to oxidize cello-oligosaccharides or cellulosic fibers, followed by reductive amination to graft amino compounds onto the cellulosic material. To this end, we first demonstrated the oxidation of cellobiose and methyl cellobiose using the laccase from Trametes versicolor and TEMPO as a mediator. Oxidation conditions were optimized with methyl cellobiose and applied to a cello-oligosaccharide mixture and cellopentaose. Using LC/MS analysis, we showed that a wide range of oxidized compounds is obtained and that the method is effective in producing acidic cello-oligosaccharides potentially of interest for the biomedical and nutraceutical fields. Then, we showed that the reactivity of oxidized cellopentaose with two aminated molecules, p-toluidine and rhodamine 123 (an aminated dye), allowed the binding of the amino compound to the oligosaccharides. Using LC/ MS and MS/MS techniques, we provided evidence for the presence of a strong, covalent amine bond between the dyes and cellopentaose, thus enlarging the chemical space accessible through this hybrid process. After completed this proof of concept, we attempted the dyeing of cotton threads. Cellulosic fibers are one of the main biosourced and biodegradable textile materials. However, chemical processing of textiles and especially the chemical methods used to covalently fix dyes are extremely polluting and harmful to health. Providing more eco-friendly alternatives is a challenge but of prime interest for a company like PILI, which was involved in the thesis project and is developing natural dyes using synthetic biology. Thus, the potential of the two-pot/two-step hybrid process was used to successfully graft p-Toluidine, rhodamine 123 and Acid Red 33 onto cotton thread. The covalent bond established between these dyes and the cotton fiber was proven for the first time. In addition, good homogeneity and wash-fastness were observed for acid Red 33 dyeing, demonstrating the robustness and applicability of the approach in real life. These original results have been patented. By testing other amino dyes, we also showed that the solubility, reactivity and structure of the aminated dye are important parameters to be addressed for dyeing optimization, which opens the way to the custom synthesis of new amino dyes suitable for this promising hybrid process

Texto completoThe manuscript presents the conversion of carbon dioxide into C3 and C4 carbohydrates using stereocontrolled chemo-enzymatic cascade reactions. The process relies on a two-step strategy with (i) the catalytic and selective 4-electron reduction of CO2 into a bis(boryl)acetal derivative followed by (ii) the stereocontrolled bio-catalyzed C-C coupling of the bis(boryl)acetal derivative into carbohydrates. The strategy developed is unprecedented and represents a new exciting approach for the use of CO2 as a Cn source for the synthesis of valuable industrially relevant enantiomerically pure biomolecules. The first chapter is a bibliographic study describing (i) an introduction to carbohydrate chemistry with a special focus dedicated to the production of carbohydrates from CO2 and formaldehyde as C1 sources and (ii) the selective and catalytic four-electron reduction of CO2 using hydroborane and hydrosilane as reductants for the formation of bis(boryl)acetal and bis(silyl)acetal derivatives and their use as formaldehyde sources or formaldehyde surrogates for the synthesis of value-added product. The second chapter presents the synthesis and reactivity of bis(boryl)acetal and bis(silyl)acetal derivatives. Notably, a new isolable bis(boryl)acetal derivative was successfully synthesized and isolated on a gram scale. The third chapter describes the stereocontrolled bioconversion of the bis(boryl)acetal derivative synthetized from CO2 into carbohydrates. Notably, an enzymatic cascade reaction was performed for the production of an enantiomerically pure C4 carbohydrate using CO2 as the only carbon source
