Abstract
Abstract tert.-Butyldimethylsilyl chloride is a useful reagent for direct 3,6-di- O -protection of D-glucal and D-galactal. The unprotected 4-hydroxy group is still accessible to other protective groups providing after selective 3,6- O -desilylation 4- O -protected derivatives. 2-Azido group introduction does not even require 4- O -protection thus affording valuable 2-azido-2-deoxy-gluco- and -galactopyranosyl donors for glycoconjugate synthesis in short and efficient routes.
