Journal ArticleDOI

Fluoro-artemisinins: When a gem-difluoroethylene replaces a carbonyl group

Guillaume Magueur, +4 more
- 01 May 2006 - 
TL;DR: In this article, an alternative reaction involving the generation of an α-CF 3 carbanion, from the corresponding bromide 6, allowed the access to the target compound 8, and could also be exemplified in sugar series.
Journal ArticleDOI

Chemical modification of chitosan by glycidyl trimethylammonium chloride. Characterization of modified chitosan by 13C- and 1H-NMR spectroscopy

Eugene Loubaki, +2 more
- 01 Jan 1991 - 
TL;DR: In this paper, a modified chitosan is discussed using elemental analysis and NMR spectroscopies, and the results are consistent with N-monoalkylation.
Journal ArticleDOI

Perfluorooctyl Bromide Polymeric Capsules as Dual Contrast Agents for Ultrasonography and Magnetic Resonance Imaging

Emilia Pisani, +15 more
- 09 Oct 2008 - 
TL;DR: Results show initial feasibility for development of these capsules toward a dual‐modality contrast agent and injections of nanocapsules in mice in vivo reveal that the initial bolus passage presents significant ultrasound enhancement of the blood pool during hepatic imaging.
Journal ArticleDOI

Trifluoromethylalkenes in cycloaddition reactions

Danièle Bonnet-Delpon, +3 more
- 01 Jan 1996 - 
TL;DR: In this paper, the influence of CF3-group on both the activation of the double bond and the stereochemistry of the cycloaddition has been evaluated, and new CF3substituted mono-and polycyclic compounds 4 and 7, highly functionalized isoxazolidines 18, 19, 22 and 23 and pyrrolidines 12, 13 and 16 have been prepared.
Journal ArticleDOI

Orally Active Antimalarials: Hydrolytically Stable Derivatives of 10-Trifluoromethyl Anhydrodihydroartemisinin†

Fabienne Grellepois, +10 more
- 11 Mar 2004 - 
TL;DR: New fluoroart Artemisinin derivatives containing polar or water-soluble functionalities at C-16 (11a-j, 12a-g) were synthesized using the key intermediate 16-bromo-10-trifluoromethyl anhydrodihydroartemisinin 10, and among them, amines 11a-c appeared to be highly in vivo efficient antimalarials on mice infected with Plasmodium berghei.
