Introduction Pulmonary hypertension (PH) is a serious medical condition subsequently complicating many other common diseases. PH seems to be increasing in the elderly; however, it has been poorly studied in this group. The aim of this study was to de

International audience; Natural fibers are frequently used as alternatives of glass fibers as polymer matrix reinforcement to form composite materials. However, their natural hydrophilicity prevents them from being easily compatible with hydrophobic

Ethyl-4,4,4-trifluoroacetoacetate (ETFAA), a powerful building block for enantiopure chirons in trifluoromethyl-β-amino acid series

Autor: Jean-Marc Paris, Jean-Christophe Plaquevent, Valérie Michaut, François Metz

Publikováno v: Journal of Fluorine Chemistry. 128:889-895

Herein are studied new transformations of ethyl-4,4,4-trifluoroacetoacetate (ETFAA), giving access to a series of enantiopure chirons bearing both a trifluoromethyl group and an amino moiety. The key intermediate is obtained optically pure by a resol

Characterisation of hydridopalladium complexes

Autor: Jonathan A. Iggo, Sébastien P. A. Hébert, Robin Whyman, Brian T. Heaton, François Metz

Publikováno v: J. Chem. Soc., Dalton Trans.. :3081-3084

The hydride complexes trans-[PdH(X)(PPh3)2](X = Cl or Br) have been prepared in good yield by hydrogenolysis of trans-[PdX(COPh)(PPh3)2] or trans-[PdXPh(PPh3)2]. They have been fully characterised by NMR and IR spectroscopic measurements and shown to

Enantioselective Organocatalytic Route to Trifluoromethyl-β-amino Acids Using Chiral Bases

Autor: Jean-Marc Paris, Valérie Michaut, Jean-Christophe Plaquevent, François Metz

Publikováno v: ChemInform. 38

Herein are studied new aspects of enantioselective (1,3) proton transfer of ethyl-4,4,4-trifluoroacetoacetate (ETFAA) amino derivatives. When catalyzed by an appropriate chiral base, ee's as high as 71% are observed. Special emphasis is given to mech

Acid-catalysed intramolecular cobalt to nitrogen aryl migration and intramolecular reverse reaction in cobalt porphyrins. Synthesis of N-phenylporphyrins

Autor: François Metz, Henry J. Callot

Publikováno v: Journal of the Chemical Society, Chemical Communications. :947

On acid treatment phenylcobalt(III)porphyrins yielded N-phenylporphyrin bases, while the reverse reaction was performed upon metallation by cobalt(II) and reduction; double labelling experiments showed that both migrations are intramolecular.
