Journal ArticleDOI
Oxidation of 5-hydroxymethylfurfural and derivatives to furanaldehydes with 2,2,6,6-tetramethylpiperidine oxide radical - co-oxidant pairs
TL;DR: In this article, the authors showed that 5-hydroxymethylfurfural (1) or 5-methylpiperidine radicals (TEMPO) 3a-d gave corresponding aldehydes 2 or 5 in fair yields.
Journal ArticleDOI
Conformational behavior of sucrose and its deoxy analog in water as determined by NMR and molecular modeling
Catherine Hervé du Penhoat,Anne Imberty,Nathalie Roques,Veronique Michon,Julio Mentech,Gérard Descotes,Serge Pérez +6 more
TL;DR: In this article, the conformational behavior of aqueous sucrose and its 2-deoxy analogue were studied by NMR and computerized molecular modeling, and steady-state NOE and NOESY data were reported along with long-range W-'H coupling constants.
Journal ArticleDOI
The use of N-alkoxycarbonyl derivatives of 2-amino-2-deoxy-d-glucose as donors in glycosylation reactions
TL;DR: An oxazolidinone was formed as the main product from the reaction of some of the glucopyranosyl bromides with alcohols of low reactivity, but the formation of all products could be interpreted by a strong participation of the alkoxycarbonylamino group.
Journal ArticleDOI
N-Allyloxycarbonyl derivatives of D-glucosamine as promotors of 1,2-trans-glucosylation in Koenigs-Knorr reactions and in Lewis acid catalyzed condensations
TL;DR: The use of suitably blocked D-glucosamine derivatives possessing the N-allyloxycarbonyl protective group of the amino function represents potential new routes to 1,2-transglucosaylations as mentioned in this paper.
Journal ArticleDOI
Esterification of unprotected sucrose with acid chlorides in aqueous medium: kinetic reactivity versus acyl- or alkyloxycarbonyl-group migrations
TL;DR: In this paper, the competition between formation, migration and hydrolysis of sucrose mono-esters and carbonates was studied and it was shown that the pre-eminent reactivity of some secondary positions persists in aqueous medium, and in particular, OH-2, even though fast subsequent migrations finally enrich the mixture in compounds substituted at the primary positions.
