Glucose is by far the most abundant monosaccharide it occurs free in fruits, plants, honey, in the blood of animals, and combined in many glycosides, disaccharides, and polysaccharides. The structure and properties of glucose will be considered in greater detail than those of the other monosaccharides, not only because of its importance, but because much of what can be said about glucose also can be said about the other monosaccharides. 

IOB activated by triflic anhydride has been used to convert thioglycosides into 0-glycosides (disaccharides). The reaction probably proceeds via a glycosyl triflate intermediate [52] ... 

Although glycosides of unsubstituted sugars have no great importance as reference compounds in carbohydrate chemistry, they are valuable as standard substrates in enzyme chemistry. Moreover, when it comes to the synthesis of natural glycosides, disaccharides, and oligosaccharides, the simple alkyl and aryl glycosides serve as prototypes.

A more stereospecific course of glycoside formation by reaction of the polymer-bound C-1 bromide with the second monosaccharide hydroxyl component involves the initial formation of a c -l 2-orthoester. This undergoes an acid-catalyzed stereospecific isomerization (Kochetkov et al., 1967) to the corresponding glycoside (disaccharide). 

Glycosides, Disaccharides and Derivatives Thereof. - Penta-O-benzoyl-a-D-fructofuranose adopts an E2 configuration. An X-ray of methyl a-D-arabinofuranoside bound to concanavalin A has been reported. ...
