Full textTo develop new synthetic tools, we developed variants of the Petasis reaction. The use of α-amino aldehydes in the Petasis reaction allowed to synthesize chiral diamines with a total diastereoselectivity. The reaction gave good results with different protective groups of the amine (sulfonamide, carbamate, amide). However, during the reaction, the amino aldehydes are epimerized and the enantiomeric excess of the prepared diamines is low (30%). The Petasis reaction was associated with the Diels-Alder reaction in a domino process to achieve the preparation of hexahydroisoindole type compounds. The domino reaction is completely diastereoselective and the molecules are obtained as enantiopure. A second domino process, using a cross-metathesis reaction followed by an intramolecular 1,4-addition, yielded compounds with a morpholine moiety in a diastereoselective manner. Intramolecular version of the Petasis reaction was developed in order to obtain carbon-six-membered rings. This reaction led to the preparation of (+)-conduramine C-4 in few steps. The cyclization has shown a surprising diastereoselectivity since the configuration between the newly formed amine and alcohol is trans. This configuration is opposite to the one obtained in the intermolecular versions

Full textPolypropylene/Titanium dioxide (PP/TiO2) nanocomposites were prepared from an original method based on the hydrolysis-condensation reactions of titanium alkoxide inorganic precursor premixed with PP under molten conditions. The synthesis is based on sol-gel method without solvent through extrusion process. A second treatment in hot water was applied in order to improve final conversion degree. First, hydrolysis-condensation reactions of titanium n-butoxide precursor were studied in model medium. Based on a kinetic equation carried out in the model medium, then the synthesis of titanium dioxide particles was transposed and modelled in polypropylene medium with high molar mass. Chemical, structural and morphological analyses highlight the in situ synthesis of bactericides PP/TiO2 nanocomposites andpresenting a particular morphological and rheological behaviour
