Texto completoIn the field of flavor and fragrance industry, the optimization of natural flavoring essential oils and extracts’ properties by biocatalysis is really interesting. In a context of sustainable chemistry, this research project is dedicated to the development of pure compounds, extracts and essential oils by enzymatic modifications. In this way, a bibliographic study has been carried out on the composition of the natural raw materials, their properties and the main biosynthetic pathways of the compounds present in the natural complex substances and some regulation elements. In the first place, according to a process of sustainable chemistry, the goal is to make healthier natural products while keeping their properties and their "naturalness". The detoxification in atranol and chloroatranol of the oak moss extract was carried out with the oak moss absolute by biocatalysis preserving their olfactory quality. Through an academic /industrial collaboration, protocols for monitoring biocatalytic transformations were established and implemented. In a third part, sustainable chemistry methodologies were used to propose new ingredients through the use of biotechnological processes based on the circular economy principle. The natural character has been preserved and the method allowed targeted transformations to develop interesting olfactory facets

Texto completoThe perfumery industry in under constant pressure from national and international regulatory bodies as well and the demands of consumers to produce novel and safe organoleptic molecules via methods which are both durable and innovative. This constant drive for innovation pushes researchers towards diverse domains of the plant kingdom which contains numerous complex natural substances (CNS). At present these natural products are a source of ingredients, however, they are equally a source of inspiration for the chemist who may identify structures of interest to be synthesised with a high degree of control (chirality, quantity, quality, consistency), as well as structural analogues to provide an improvement of the olfactory properties (notes, intensity).This manuscript presents an extended analysis of the distillate of a concrete of the plant Ocimum gratissimum via GC-O complemented with GC-MS analysis. This study has also enlighted the chemical composition of the extract, characterisation of the poorly described (E)-methyl cinnamate chemotype, olfactory evaluation by a master perfumer and the identification of the principal olfactive compounds. This work simultaneously explores multistep asymmetric synthetic strategies in the aim of obtaining the different enantiomers of vetispira-2(11),6-dien-14-al. This compound is known to be an important component of agar wood essential oil and largely responsible for its particular odour. Currently no syntheses of this compound have been published. An FeCl3 catalysed acetylation of α,β-unsaturated compounds was optimised and applied to the synthesis of 24 different heterocyclic spirocycles, which are to be submitted to a master perfumer for the evaluation of their notes and olfactory interest
Richieu, Antoine. "Synthèse totale de la vescaline, substance naturelle bioactive de la famille des ellagitannins C-arylglucosidiques". Thesis, Bordeaux, 2017. http://www.theses.fr/2017BORD0937/document.
Texto completoC-arylglucosidic ellagitannins are polyphenolic compounds biosynthesized through the secondary metabolism of various plants, in particular from the Fagaceae family such as oak and chestnut. Vescalin, which belongs to this class of plant polyphenols, displays interesting biological activities, with antiviral and antitumoral properties. More specifically, it inhibits topoisomerase 2α, a targeted enzyme in chemotherapy used in cancer treatment, and have also an activity against the cytoskeletal filamentous actin. Unique structure of vescalin displays a NonaHydroxyTriPhenoyl moiety (NHTP) linked to an open chain D-glucose with a C-arylglucosidic bond. The total synthesis of vescalin constitutes the main goal of this doctoral work. Synthetic routes employ in part chemical methods previously used for the total synthesis of 5-O-desgalloylepipunicacortein A in addition to new methodologies. Therefore, the C-arylglucosidation method and chemical yield have been improved and an efficient intramolecular terarylic coupling between a HexaHydroxyDiPhenoyl moiety (HHDP) and a galloyl unit has been developed. Taking advantage of the synthetic strategy elaborated for vescalin total synthesis, three additional C-arylglucosidic ellagitannins were obtained: punicacortein A, epipunicacortein A and castalin

Texto completoThis thesis aims at the study of the chemical and biogenetic origin of specialized guanidine-alkaloid metabolites produced by sponges from the Mediterranean Sea.The work is divided into three main parts: 1) isolation of alkaloids produced by sponges of the Poeciloscerida order; 2) biosynthesis of crambescin C1 by in-vivo 14C-feeding experiments with Crambe crambe sponge; 3) biomimetic synthesis of crambescin A2 448 and derivatives. The main focus of the thesis will be the family of cyclic-guanidine alkaloids "crambescins", produced by the red incrusting sponge Crambe crambe.These alkaloids were discovered in the early 90s and despite the large interest on their biological activities, ecological roles, and synthesis, their biosynthesis is still unknown.The only available biomimetic synthesis of crambescins was based on a fully polyketide origin hypothesis. Recently our groups suggested an alternative biosynthetic hypothesis in which the guanidine-core would be originated from a condensation between a guanidinated pyrrolidinium derived from arginine and a beta-keto fatty acid. Based on this hypothesis, we designed a biosynthesis experiment that inspired a biomimetic synthesis route to access the crambescins and derivatives. The insights from these studies are the first experimental conclusions about the biosynthesis of crambescins. Finally, this work leads to a better comprehension of the biochemistry involved in guanidine marine alkaloids of complex structures
