Gj. Boons et al., DISPIROKETALS IN SYNTHESIS .5. A NEW OPPORTUNITY FOR OLIGOSACCHARIDE SYNTHESIS USING DIFFERENTIALLY ACTIVATED GLYCOSYL DONORS AND ACCEPTORS, Tetrahedron letters, 34(52), 1993, pp. 8523-8526
The reactivity of dispiroketal protected thioglycosides makes them use
ful new precursors for oligosaccharide synthesis as is illustrated by
the preparation of a protected pentasaccharide unit common to the vari
ant surface glycoprotein of Trypanosoma blucei.
