A significant effect of a lithium salt in the stereocontrolled synthesis of α-D-ribofuranosides
Uchiro, Hiromi,Mukaiyama, Teruaki
, p. 271 - 272 (1996)
Lithium bis[(trifluoromethyl)sulfonyl]imide was found to be a new and effective additive in the stereocontrolled synthesis of α-D-ribofuranosides from 2,3,5-tri-O-benzyl-D-ribofuranose and several alcohols while β-anomers were formed in the absence of the
Perchloric acid in 1,4-dioxane and perfluorooctanesulfonic acid as practical catalysts for the stereoselective glycosylation of 1-O- acetylglycosides

A perchloric acid solution in 1,4-dioxane and perfluorooctanesulfonic acid was found to be practical catalysts for the stereoselective glycosylation of 1-O-acetylglycosides. Either the α- or β-anomer of the disaccharide, methyl 2,3,4-tri-O-benzyl-6-O-(2,3,5-tri-O-benzyl-D- ribofuranosyl)-α-D-glucopyranoside, was synthesized with complete stereoselectivities simply by changing the solvent. Epimerization of the kinetic product can effectively be suppressed in ether by the excess use of the polyoxygenated substrates.
An efficient glycosylation reaction of 1-hydroxy sugars with various nucleophiles using a catalytic amount of activator and hexamethyldisiloxane
Mukaiyama,Matsubara,Hora
, p. 1368 - 1373 (2007/10/02)
In the presence of hexamethyldisiloxane and anhydrous calcium sulfate, a catalytic amount of activator such as tin(II) trifluoromethanesulfonate, ytterbium trifluoromethanesulfonate, lanthanum trifluoromethanesulfonate or tin(II) chloride smoothly promote
