General Introduction

A glycoside may be defined as a mixed acetal resulting from the exchange of the hydrogen atom of the hemiacetal group of a cyclic aldose or ketose by an alkyl or aryl group. Sugars are found in nature in a wide variety of forms and in chemical association with a vast number of other compounds, including other sugars; many of these derivatives have key roles to play in biological processes as well as providing structure and form in high-molecular-mass assemblies. Attachment of sugar units to other molecules can be made via O-, N-, S-, or C-glycoside bonds to the anomeric center, but in nature O-glycosylation predominates. Indeed, O-glycosides are interesting compounds from both biological and chemical points of view and some of them are valuable glycosylating agents for the synthesis of other classes of sugars.
