Reactions at Oxygen Atomsific hydroxy groups as well as the selective removal of a part of protecting groups in the context of nucleoti- de synthesis. This progress originates from the necessity of obtaining long-chain natural nucleotides without contamination by analogs or other impurities.

Heteroatom Exchangetions as chiral ligands for asymetric synthesis and also as biological intermediates. The syntheses of these classes of carbohydrates require specific methods that will be reviewed in the following chapter.

Lehrbuch der technischen Mechaniksynthesis. These derivatives might be divided into four main classes depending on the size of the heterocyclic ring i.e., oxiranes (e.g., 1), oxetanes (e.g., 2), THF derivatives (e.g., 3), and THP derivatives (e.g., 4; Fig. 1.). The latter are very rare and only limited examples can be found in literature.

Deoxygenationsugars. Deoxy sugars of this type are found in many naturally occurring oligosaccharides, more commonly as deoxyaldoses than as deoxyketoses. Three of them are particularly important: (i) L-rhamnose (6-deoxy-L-mannose) found in plant and also in bacterial polysaccharides;
