Enantioselective organocatalysis with size-defined chitosan oligomers

, 2014
Des oligomères de taille définie de chitosane ont été préparés et testés en tant qu'organocatalyseurs dans des réactions d'aldolisation énantiosélectives. Les précurseurs de ces catalyseurs sont obtenus en une seule étape par une réaction d'acétolyse contrôlée de la chitine, second polysaccharide le plus abondant.
