SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
In this part other procedures of glycosylation reactions by direct activation are presented. We will focus on the n-pentenyl glycoside, the O-alkylation and the trichloroacetimidate methods. The use of glycosyl phosphates and glycals in glycosidation reactions are also discussed. Updated examples of these glycosylation methodologies involving total synthesis of oligosaccharides and related compounds are considered.
Keywords:
