Molecular sieves promote stereocontrolled αα-disaccharide formation via direct dimerization of free sugars

Some commercial molecular sieves promote direct dimerization of free pyranose and furanose sugars stereoselectively into the corresponding α,α-disaccharides.

2-Allylphenyl glycosides as glycosyl donors for sugar coupling

Glycosylations employing 2-allylphenyl glycoside, a new type of stable glycosyl donor, were optimized and explored with a variety of acceptors promoted by ICl/AgOTf. The utility of the protocol was further demonstrated with an efficient synthesis of the disaccharide fragment of bleomycins.

Formation of O-glycosidic linkages from 1-hydroxy sugars by bismuth(III) triflate-catalyzed dehydrative glycosidation

This paper describes the direct formation of various O-glycosidic linkages from 1-hydroxy sugars by bismuth(III) triflate-catalyzed dehydrative glycosidation. The condensation reactions of 1 -hydroxy sugars with some primary alcohols in the presence of on

2-Allyloxyphenyl glycoside as a new and stable type of glycosyl donors

A high-yielding coupling of a new and stable type of glycosyl donors, namely 2-allyloxyphenyl glycoside, with a variety of alcohols via NIS/TfOH reagent combination as effective activators at room temperature is described here.

Sulfoxide Covalent Catalysis: Application to Glycosidic Bond Formation

A versatile glycosylation reaction is used to establish the process of sulfoxide covalent catalysis. Hemiacetals are activated by benzenesulfonic anhydride and a dialkyl sulfoxide catalyst, nBu2SO, for coupling with various nucleophiles (Nu; se

Synthesis of methyl O-α-D-mannosyl-(1→4)-[(3-O-methyl-α-D-mannosyl) -(1→4)-]n3-O-methyl-α-D-mannosides (n = 0, 1, and 2) via dehydrative glycosylation

Methyl O-α-D-mannopyranosyl-(1→4)-[(3-O-methyl-α-D-mannopyranosyl -(1→4)-]n3-O-methyl-α-D-mannopyra-nosides (n = 0, 1, and 2), the lowest homologs related to the 3-O-methylmannose polysaccharides (MMP) from Mycobacterium smegmatis, were synthesized via dehydrative glycosylation reactions. The reagent systems, composed of p-nitrobenzenesulfonyl chloride, silver trifluoromethanesulfonate, and triethylamine, of p-nitrobenzenesulfonyl chloride, silver trifluoromethanesulfonate, and 1, 8-diazabicyclo[5.4.0]undec-7-ene, and of trimethylsilyl trifuloromethanesulfonate and pyridine were useful.

Rational design and synthesis of a 1,1-linked disaccharide that is 5 times as active as sialyl Lewis X in binding to E-selectin

We describe here a rational design and synthesis of (3-O-carboxymethyl)-β-D-galactopyranosyl α-D-mannopyranoside which is 5 times as active as sialyl Lewis X in binding to E-selectin and also effective against P- and L-selectin. A new method for the 1,1-g

TMS triflate induced synthesis of 1,1'-disaccharides from 1-hydroxy sugars

A variety of 1,1'-disaccharides have been prepared by TMS triflate induced coupling of 1-hydroxy sugars in reasonable yield.

Synthesis and glycosylation shift of 1,1'-disaccharides

Nineteen kinds of nonreducing 1,1'-disaccharides have synthesized by modified Koenigs-Knorr method, and characterized by NMR. The glycosylation shift of each anomeric carbon has been estimated.
