Conclusions
-
1.
We have proposed a new method for the de-O-tritylation and de-O-acetonation of sugar derivatives by pyridinium perchlorate.
-
2.
We have used this method for the synthesis of trisaccharide derivatives that are models for the stepwise synthesis of polysaccharides constructed from repeating oligosaccharide units.
