Glycosylation, chemical general approaches

The only general approach to the chemical synthesis of glycosyl esters of nucleoside pyrophosphates thus far found useful involves... 

In chemoenzymatic synthesis, the glycosylamino acids are obtained by enzymic glycosylation and used as building blocks in combinatorial libraries creation [15]. This latter technology requires, first, the solution and implementation of several technical problems to be considered a general method-like chemical approach. Use of enzymatic methods can avoid some regio- and...
