Scope and limitations of the double [4+3]-cycloadditions of 2-oxyallyl cations to 2,2 '-methylenedifuran and derivatives

Pierre Vogel, Marc-Etienne Schwenter, Kai Torsten Meilert

The reactivity of various 2-oxyallyl cations toward 2,2'-methylenedifuran (1b), 2,2'-(hydroxymethyl)difuran (1c), 2,2'-(trimethylsilylmethylene)difuran (1d), and di(2-furyl)methanone (1e) has been explored. Difuryl derivatives 1c, 1d, and le refused to und ...

Asymmetric synthesis of 1-aminopentadecane-3,5,7,9,11,13,15-heptols and of 1,15-diaminopentadecane-3,5,7,9,11,13-hexols and derivatives

Pierre Vogel, Sandrine Gerber

Starting from 2,2'-methylenedifuran, enantiomerically enriched (98%) (3R,5S,7R,9S,11R,13R)- and (3R,5S,7S,9R,11R,13R)-15-amino-5,7,9,11-tetrahydroxy-3,13-bis(4-methoxyb enzoyloxy)pentadec-1-yl) pivalate were prepared as well as (3R,5R,7R,9R,11S,13S)-1,15-d ...

Derivatives of (2R,3R,4S)-2-Aminomethylpyrrolidine-3,4-diol are Selective alpha-Mannosidase Inhibitors

Pierre Vogel, Sandrine Gerber, Inmaculada Robina, Eliazar Rodriguez Garcia, Raynald Demange

A collection of (2R,3R,4S)-3,4-dihydroxypyrrolidin-2-yl derivatives have been tested for their inhibitory activities toward 25 glycosidases. Competitive (K-i=7.4 VM) and selective inhibition of alpha -mannosidase from jack bean has been found for (2R,3R,4S ...

Using Multiple Time Scales in the Framework of Multi-Stream Speech Recognition

Hervé Bourlard, Astrid Hagen

In this paper, we present a new approach to incorporating multiple time scale information as independent streams in multi-stream processing. To illustrate the procedure, we take two different sets of multiple time scale features. In the first system, these ...

A thermodynamic model for MgSiO3-perovskite derived from pressure, temperature and volume dependence of the Raman mode frequencies

Philippe Gillet

Raman spectra of MgSiO3-perovskite (Mg-pv) were recorded at simultaneous high-pressure and low-temperature conditions. This allowed to estimate characteristic frequencies (nu(i)) and other mode parameters as a function of both pressure and temperature. The ...

5-Aminolevulinic acid and its derivatives: physical chemical properties and protoporphyrin IX formation in cultured cells

Hubert van den Bergh, Georges Wagnières, Matthieu Philippe Emmanuel Zellweger, Pascal Uehlinger

Protoporphyrin IX (PpIX) is used as a fluorescence marker and photosensitizing agent in photodynamic therapy (PDT). A temporary increase of PpIX in tissues can be obtained by administration of 5-aminolevulinic acid (ALA). Lipophilicity is one of the key pa ...

Synthesis of alpha-C(1 -> 3)-mannopyranoside of N-acetylgalactosamine, a new beta-galactosidase inhibitor

Pierre Vogel, Raynald Demange

Radical C-glycosidation of a 3-methylidene-7-oxabicyclo[2.2.1]heptan-2-one derivative with acetobromomannose gave a alpha-C-mannopyranoside that was converted into alpha-D-ManpCH(2)(1-->3)-D-GalNAc, a C-disaccharide that inhibits beta-galactosidase from ja ...
