The first topic is reviewed very shortly, showing only the most important reactions having the great impact on the chemistry of sugars, as well as on the stereoselective organic synthesis. Such transformations are described in many excellent reviews. 

There are many useful transformations dealing with the rearrangement of the orientation of substituents, transposition of the double bond (more precisely the unsaturation ), etc., which change the properties and the character of the molecule but leave the skeleton of the sugar untouched.
