Electrospray ionization mass spectrometry: a key analytical tool for the characterization of regioselectively derivatized maltooligosaccharides obtained starting from natural b-cyclodextrin
Lesur, David; Gassama, Abdoulaye; Moreau, Vincent; Djedaïni-Pilard, Florence; Brique, Arnaud; Pilard, Serge (Published online in Wiley InterScience (www.interscience.wiley.com). DOI: 10.1002/rcm.2369, 2006)The development of natural cyclodextrins (CDs) for various industrial applications (agroalimentary, cosmetic or pharmaceutical) constitutes a continuous challenge. For the integration of these agricultural plant products ... -
Synthesis and characterization of regioselectively monoderivatized maltooligosaccharides through a combination of tandem mass spectrometry and enzymatic hydrolysis studies
Gassama, Abdoulaye; Lesur, David; Brique, Arnaud; Thiebault, Nicolas; Djedaïni-Pilard, Florence; Pilard, Serge; Moreau, Vincent (2013)Recently, we have designed chemical strategies leading to C-6 perfunctionalized linear maltoheptaose derivatives via the acetolysis of persubstituted β-cyclodextrin (β-CD) at the 6-positions. This approach has now been ... -
Synthesis of regioselectively and uniformly modified maltoheptaose derivatives from cyclomaltoheptaose precursors
Lesur, David; Gassama, Abdoulaye; Moreau, Vincent; (Elsevier, 2005)Dérivés de l'heptadeoxy-6I – VII-halo, -azido et de l'hepta-6I – VII S-hepta (N-Boc-2-amino) éthyl-6I – VII-heptathiomaltoheptaose ont été préparés par acétolyse des dérivés de b-cyclodextrine modifiés par la per-C-6 ...
