Texte intégralThe decrease in easily accessible petrochemical resources has given over the past ten years a growing interest in the use of raw materials of renewable origin. The primary wood processing industry generates large amounts of waste each year which are currently either recycled to other sectors such as paper mills or the panel industry, or used as a source of energy, and therefore to markets with low added value. The project is situated in this context of sustainable development, circular economy and valorization of co-products of the wood industry by the exploitation of secondary metabolites present in wood, such as phenolic compounds, and more precisely flavonoids, which are indeed of interest in various fields because of their biological activities.The objective of this work is to functionalize accessible and abundant compounds in order to obtain polyfunctional compounds with 2-in-1 properties and thus be able to simplify cosmetic formulations. Functionalization has been considered by two routes: chemical hemisynthesis and/or enzymatic catalysis.By chemical hemisynthesis we were able to obtain bi-modular compounds by combining a fatty acid and a non-glycosylated flavonoid, in this case we worked with catechin. Direct acylations on the phenolic hydroxyls of catechin have been studied and the regioselectivity has been demonstrated by NMR spectroscopy and confirmed by molecular modelling. We have also obtained tri-modular compounds by chemical hemisynthesis by combining different amino acids, as well as fatty acids of variable length with catechin. Three different trimodular structures have been synthesized.By enzymatic hemisynthesis we have synthesized tri-modular compounds, from glycosylated flavonoids, rutin and narignin, aiming for the grafting of fatty acids of different chain lengths but this time on the glycosidic part of the flavonoids. We have also synthesized penta-modular compounds resulting from the grafting of a dicarboxylic acid on naringin or rutin. These compounds comprise two flavonoid entities grafted on either side of the carbon chain of the diacid.At the end of these syntheses, the physico-chemical properties of the products were studied, in particular their solubility in water, their anti-radical properties but also the surfactant properties. Some biological activities have also been studied such as antiproliferative activity against CaCo2 cells. In order to understand the effect of the structure of the compounds on their antioxidant capacity, molecular modeling work has been undertaken; correlations between the antioxidant activity of compounds determined experimentally and chemical reactivity descriptors calculated in silico were sought
