Повний текст джерелаIsosorbide is a chiral dianhydrohexitol obtained in enantiomerically pure form by double dehydration of sorbitol, a major product of the starch industry resulting from hydrogenation of glucose. Isosorbide has been increasingly studied these last twenty years, mainly thanks to industrial companies, such as Roquette (France) that implemented the production to 20,000 tons a year. This availability allowed the promotion of isosorbide applications in various fields: polymers (polyethylene isosorbide terephthalate), surfactants, solvents (dimethyl isosorbide) and pharmacy (isosorbide dinitrate). Isosorbide structural properties opened its investigation as a chiral inducer either as a ligand, an auxiliary or a phase transfer catalyst. Other isohexides (isomannide, isoidide) were much less studied. These diastereomeric conformationally rigid structures offer a large diversity of functionalizations to tune their electronic and steric properties. Isohexides are promising candidates for the development of biosourced organocatalysts. Very recently, Friedel-Crafts enantioselective alkylation of indole mediated by thiourea organocatalysts derived from isohexides has been described. In this thesis, the functionalization of isohexides into amino derivatives is reported. A first serie of amino-alcohols, amino-ethers and diamines is reported. A second generation of α-amino amides and 1,2-diamines is then obtained via amidation. These nitrogenfunctionalized derivatives are screened as organocatalysts for the asymmetric synthesis of warfarin (with results up to 20% of yield and 28% of e.e.) and for isatin aldolisation (with results up to 73% of yield and 33% of e.e.)

"Design et utilisations de complexes organométalliques intercalés dans la bentonite pour des réactions d’insertion ou de complexes organométalliques chiraux pour des réactions de cyclopropanation asymétrique."

Повний текст джерелаThis thesis is divided in two independent parts. The first concerns the development of new heterogeneous catalytic systems involving intercalation of ethylacetonate copper and iron complexes in a clay: the bentonite. For this purpose, the bentonite is purified prior to the inclusion of the two complexes. A study of the catalytic activity of these two materials was performed with ethyl diazoacetate to form ethyl fumarate and maleate. Carbene insertion reactions were then studied with amines and alcohols to form respectively a-oxa and a-aza ethyl acetate derivatives in 60 to 95% yields. The aim of the second part is to study, the homogeneous catalytic asymmetric cyclopropanation reaction of alkenes catalyzed by copper (I) complexes; the cyclopropane unit being present in many compounds presenting biological activities. For that purpose, the synthesis of new oxazolines and imines ligands derived from isosorbide and isomannide, two compounds of the biomass was performed. Complexed with copper (I), these ligands were evaluated for the asymmetric cyclopropanation of styrene, of a-methylstyrene, indene, of oct-1-ene in the presence of ethyl diazoacetate. Cyclopropanation of cyclopentene was similarly performed. Various parameters were examined to determine the best reaction conditions. The most significant results in terms of diastereoselectivity and enantioselectivity were obtained in the cyclopropanation of styrene with a complex oxazoline/CuI (diastereoselection trans/cis: 90/10, ee : 93% for the trans isomer). Furthermore, we showed that a catalytic system formed by a diimine and Cu(CH3CN)4PF6 gave similar stereoselectivities for the cyclopropanation of styrene and a-methyl styrene, indicating that the system is less dependent on the nature of the substrate
