AuIII-halide/phenylacetylene-catalysed glycosylations using 1-o-acetylfuranoses and pyranose 1,2-orthoesters as glycosyl donors

1-O-Acetylfuranoses and pyranose 1,2-orthoesters were activated with an AuIII halide/phenylacetylene relay catalyst system, and they acted as excellent glycosyl donors. Thus, 1-O-acetyl-D-ribofuranose, 1-O-acetyl-D-lyxofuranose, and 1,2-orthoesters selectively gave the corresponding 1,2-trans glycosides, whereas 1-O-acetyl-D-arabinofuranose and 1-O-acetyl-D-xylofuranose both gave mixtures of 1,2-trans and 1,2-cis glycosides, with the 1,2-trans glycosides predominating. A new glycosylation method has been developed for 1-O-acetylfuranoses and pyranose 1,2-orthoesters, using AuIII halides and phenylacetylene as relay catalyst systems. Good anomeric selectivity was observed for 1-O-acetylfuranoses, and excellent selectivity was observed for pyranose 1,2-orthoesters. The corresponding glycosides were formed in moderate to good yields.

Propargyl/methyl furanosides as potential glycosyl donors

Transfuranosylations are not well studied though many similar studies exist for transpyranosylation; herein, we report that propargyl/methyl d-ribf- and d-lyxf- give only 1,2-trans glycosides whereas d-araf- and d-xylf- result in a mixture of 1,2-trans an

Tandem catalysis strategy for direct glycosylation of 1-hydroxy sugars. Methoxyacetic acid as an effective catalytic mediator

1-Hydroxy sugars were dehydratively coupled with a variety of alcohols including thiophenol in the presence of a catalytic amount of ytterbium(III) triflate [Yb(OTf)3] and methoxyacetic acid to give the corresponding glycosides in good to excel

Dehydrative glycosylation of tri-O-benzylated 1-hydroxyribofuranose catalyzed by a copper(II) complex

A phosphine/Cu(II) complex catalyzes the dehydrative glycosylation of tri-O-benzylated 1-hydroxyribofuranose to give the ribofuranoside with high stereoselectivity.

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.

Trityl salt catalyzed stereoselective glycosylation of alcohols with 1-hydroxyribofuranose

In the presence of a catalytic amount of several trityl salts, 2,3,5-tri-O-benzyl-D-ribofuranose smoothly reacted with alcohols to give various β-ribofuranosides in high yields with high stereoselectivity while reversed stereoselectivity was observed in t
