New and general synthesis of β-C-glycosylformaldehydes from easily available β-C-glycosylpropanones
Norsikian, Stephanie,Zeitouni, Jennifer,Rat, Stephanie,Gerard, Sylvie,Lubineau, Andre
, p. 2716 - 2728 (2008/03/14)
A highly effective method for the introduction of a formyl group at the anomeric position of pyranosides was developed via enolisation of β-C-d-glycopyranosylpropan-2-one using thermodynamic conditions then oxidative cleavage of the more substituted doubl
A convenient new route to protected and free 2,6-anhydro-d-glycero-d-gulo- heptoses (1-formyl-β-D-glucopyranosides)
Zeitouni, Jennifer,Norsikian, Stéphanie,Lubineau, André
, p. 7761 - 7763 (2007/10/03)
A new and efficient process has been developed for the synthesis of 1-formyl-β-glucopyranosides from D-glucose.
Bromoketone C-glycosides, a new class of β-glucanase inactivators
Howard, Steven,Withers, Stephen G.
, p. 10326 - 10331 (2007/10/03)
Although reliable methods have been developed for the labeling of the active site nucleophiles in glycosidases, no such reliable method has been developed for the identification of the acid/base catalyst. To address this problem two novel bromoketone affi
Epimerization of α- to β-C-Glucopyranosides under Mild Basic Conditions
Allevi, Pietro,Anastasia, Mario,Ciuffreda, Pierangela,Fiecchi, Alberto,Scala, Antonio
, p. 1275 - 1280 (2007/10/02)
A number of β-C-glucopyranosides having an activated methylene or methine group bonded to the anomeric carbon are obtainable in quantitative yield from the corresponding α-isomers by simple equilibration catalysed by various bases at room temperature.
Oxygenated Allylic Silanes: Useful Homoenolate Equivalents for the Stereoselective C-Glycosidation of Pyranoside Derivatives
Panek, James S.,Sparks, Michelle A.
, p. 2034 - 2038 (2007/10/02)
Acylated C1-oxygenated allylic silanes, trimethylsilane (1a), trimethylsilane (1b), and ethyl 2-propenyltrimethylsilane-1-carbonate (1c), function as homoenolate equivalents in BF3*OEt2-catalyze
USE OF 1JC1,H1 VALUES FOR THE STEREOCHEMICAL DETERMINATION OF C-GLYCOSIDES: A SIMPLE TWO DIMENSIONAL NMR PROTOCOL
Sparks, Michelle A.,Panek, James S.
, p. 407 - 410 (2007/10/02)
A combination of three two-dimensional homo- and heteronuclear correlation methods have been used to determine the stereochemistry of C-glycosides derived from the reaction of 1-acetyloxy allylic silanes with pyranosi
