is compatible with glycosylation reactionsusing trichloroacetimidate donors. The deep-red colour of the Az-group greatly facilitates the purification of carbohydrate building blocks and the monitoring of couplingreactions. Of particular note is that the Az-group can be selectively introduced on diol systems and removed in the presence of esters, such as acetates.
