The (-)-?-bisabolol is a natural product available in a large quantity in Brazil. It is extracted of several specimens of trees and has recognized biological activity that made it a so interesting product for cosmetic and pharmaceutic industries. The research has as mean goal the modification of (-)-?-bisabolol a natural product. The modification has intended, improve the biological activity or create new biological activity. The methods applied always consider condition to protect the environment (Green Chemistry). The research has three main parts: amino reduction, oxidation and cycloaddition. The first part based on the reaction to synthesize the imines (N-benzylphenilmethanoamine) and with the amine reduction synthesis the secondary amine. A second part was oxidizing the secondary amines and bisabolol. The third part is a research about cycloaddition. The amines oxidation (dibenzylamine e 1,2,3,4-tetrahydroisoquinoline) gave the nitrones [N-benzylidenebenzylamine N-oxide and 3,4-dihydroisoquinoline N-oxide] respectively. The Bisabolol oxidation (epoxidation reaction) gave a mix of bisabolol oxide: The Bisabolol oxide B, 1-methyl-1-[5-(4-methyl-3-ciclohexenyl)tetrahydro-2-furanyl]ethyl alcohol and The Bisabolol oxide A, (3S)-2,2,6-trimethyl-6-(4-methyil-3-ciclohexenyl) tetrahydro-2H-3-piranol. The alilic oxidation from Bisabolol also was achieved and gave the tetrahydro-2,2,6-trimethyl-6-(4-methyl-3-cyclohexen-1-yl)-4H-pyran-4-one. The cycload-dition [1+2] between diclorocarbene and bisabolol gave, 4-(2,2-dicloro-3,3-dimethylciclopropil)-2-(7,7-dicloro-6-methylbiciclo[4.1.0]hept-3-yl)-2-butanol. The cycloaddition [2+3] with nitrones (3,4-dihydroisoquinoline N-oxide) and dipolarophile (butyl vinyl ether) gave the isoxazolidine 1,5,6,10b-tetrahydro-2H-isoxazolol[3,2-a]isoquinoline-2-yl butyl ether.

• l'étude de la réactivité des N-alcényloxazolidin-2-ones en tant que nouveaux dipolarophiles aza-substitués en cycloaddition 1,3-dipolaire à demande inverse vis-à-vis de nitrones.
• la mise en jeu de nitrones aspartiques originales en cycloaddition vis-à-vis de différents alcènes pour fournir des précurseurs d'aspartates α-substitués par une chaîne fonctionnelle.
Dans un premier temps, nous avons mis au point deux méthodes inspirées de celles de la littérature en partant d'une oxazolidin-2-ones pour synthétiser les N-alcényloxazolidin-2-ones: (i) vinylation cupro-catalysée utilisant un bromure d'alcényle, (ii) condensation avec un aldéhyde. Ces méthodes simples, générales, directes et à hauts rendements nous ont permis d'accéder aux N-alcényloxazolidin-2-ones de structure diverse.
Ces N-alcényloxazolidin-2-ones ont montré une grande réactivité en tant que dipolarophile vis-à-vis de diverses nitrones dans différentes conditions : thermiques (avec/sans solvant) et promues par TMSOTf. Les 5-aza-isoxazolidines diversement substituées originales ont été obtenues avec des rendements élevés mais de faibles stéréosélectivités. Cette limitation − due à l'instabilité configurationnelle des nitrones activées et à la flexibilité conformationnelle des N-alcényloxazolidin-2-ones − a été résolue par utilisation de la nitrone chirale à géométrie fixe de Tamura : les adduits trans-β sont obtenus avec d'excellents sélectivités
La tranformation des adduits issus de la N-benzyl-α-carbonyloxyéthylnitrone en dérivés aspartates carboxy-différenciés a été ensuite étudiée par une séquence en deux étapes (i) ouverture du cycle isoxazolidinique en aspartimide via N-quaternarisation par benzylation (ii) attaque chimiosélective d'un hétéronucléophile sur la fonction amide. Les aspartates carboxy-différenciés ont été obtenus avec de bons rendements, des excès énantiomériques élevés en version non-racémique, et un grand degré de diversité fontionnelle en ω (ester, amide, acide).
L'étude a été étendu à la cycloaddition 1,3-dipolaire des N-vinyloxazolidin-2-ones β,β-difluorées originales avec la N-benzyl-α-carbonyloxyéthylnitrone : les 4,4-difluoro-5-aza-isoxazolidines sont obtenues avec de bons rendements malgré une faible stéréosélectivité probablement due à un mécanisme non-concerté.
Notre étude a été complétée par l'accès à des dérivés d'α-aminoacides α,α-disubstitués via cycloaddition 1,3-dipolaire mettant en jeu de nouvelles nitrones aspartiques d'une stablilité configurationnelle inédite. Ce type de nitrones − préparé facilement par addition d'une N-benzylhydroxylamine sur un acétylènedicarboxylate – a montré une grande réactivité vis-à-vis d'une large gamme d'alcènes de différents natures électroniques. Les adduits issus des éthers vinyliques ont été obtenus avec de hauts sélectivités trans. L'extension asymétrique utilisant soit un éther vinylique chiral , soit une nitrone chirale a été effectuée et a permis l'obtention facile des adduits diastéréomériquement enrichis. A partie de ces adduits, un premier accès réussi aux dérivés aminoacides α,α-disubstitués a été réalisé en trois étapes. La diversification de cette méthodologie a été effectuée en utilisant une nitrone aspartique carboxy-différenciée.

The design of new fine chemicals from biomass and platform molecules has recently become a very active field of research. 5-Hydroxymethylfurfural (HMF) is considered as one of the most promising renewable building blocks derived from carbohydrates, due to the rich chemistry offered by its high level of functionality. Its glucosylated analogue glucosyloxymethylfurfural (GMF), though much less available, is also an interesting biobased furanic aldehyde able to provide a range of novel architectures which include a remaining full carbohydrate moiety. The present thesis is a contribution to the use of these two building blocks for the design of novel fine chemicals, using notably two reactions, namely the Morita-Baylis-Hillman reaction, and the cycloaddition of nitrones. The application of these strategies for designing novel surfactants was also investigated. First, we investigated the MBH reaction of HMF and GMF with cycloalkenones using pure water as solvent. New functionalized scaffolds have been prepared in mild and safe conditions with remarkable atom-economy by this route for the first time. Then we investigated the possibility to run MBH reactions of HMF and GMF with acrylates or other alkenes in absence of any solvent. The 1,3-dipolar cycloaddition reactions of nitrones obtained from HMF and GMF offer novel synthetic routes towards biobased isoxazolidines. The sequence “nitrone formation-cycloaddition reaction” can be performed either in a multicomponent approach or in a stepwise one. In the last part, we addressed the possibility to use these two routes for the design of novels biobased surfactants, in the frame of a collaboration with Prof Véronique RATAJ and Dr Fermin ONTIVEROS of the CISCO team of the UCCS research unit in Lille. Preliminary results on their surfactants properties have been obtained, and indicate a real interest of these compounds which exhibit easily adjustable properties based on simple structural variations, and which are obtained in an easy straightforward and original synthetic sequence

During this thesis, we were interested to develop two different ways of 1,3 dipolar cycloaddition to reach enantiopure disubstituted polyfunctionnal amino acids.We have described in a first part the diastereoselective 1,3-dipolar cycloaddition between an aspartic nitrone and chiral vinyl ethers. The aspartic ketonitrone and vinyl ether of (R) or (S) stericol led to high diastreocontrols. This control is due to the stability of the nitrone under (E) geometry which favors the exo approach, facially controlled by the dipolarophile. The chemoselective N-deprotection of this adduct leads to a diastereo- and enantiomerically pure isoxazolidine which affords the target DAA after N-acylation and N-O ring opening by a dismutative pathway. In a second part, we describe the synthesis of isoxazolidines obtained by organocatalytic enantioselective 1,3-dipolar cycloaddition between an alanine-derived nitrone and an enal or an ynal as the dipolarophile. With enals β-substituted by alkyl groups, good diastereoselectivities and ees were obtained in the presence of the MacMillan catalyst. These organocatalyzed conditions can be applied to a range of carboxy ketonitrones, and to different enals, provided an appropriate choice of the co-acid. Ynals show no reactivity under these organocatalytic conditions, although they lead regioselectively to polyfunctional quaternary isoxazolines under thermal conditions.Our study was achieved by the access of polyhydroxylated amino acids derived from opening adducts obtained by the enantioselective route using enals as dipolarophiles. This study allows to envisage the enantioselective synthesis of analogs of myriocin
