Abstract
Stereoselective construction of a variety of β-glycosides can be achieved using abundant and inexpensive K(2)CO(3)-mediated stereoselective anomeric O-alkylation of sugar lactols with primary electrophiles. In addition, application of this methodology to the synthesis of various azido-modified glycosphingolipids has been accomplished in good yields and excellent anomeric selectivity using sphingosine-derived primary triflate.
