Dispiroketals in synthesis (part 5): A new opportunity for oligosaccharide synthesis using differentially activated glycosyl donors and acceptors

Article abstract of DOI:10.1016/S0040-4039(00)61375-8

The reactivity of dispiroketal protected thioglycosides makes them useful new precursors for oligosaccharide synthesis as is illustrated by the preparation of a protected pentasaccharide unit common to the variant surface glycoprotein of Trypanosoma bruce
