• Formation of Homooligosaccharides Using Base-Promoted Glycosylation of Unprotected Glycosyl Fluorides

  Homooligomeric saccharides are of general interest with potential applications in chemical, pharmaceutical, and food industry as well as for materials with novel properties. This contribution describes a methodology of a base-promoted "single step self-oligomerization" of glycosyl fluorides as donors leading to oligomers with up to similar to 25 saccharide units. The influences of base and reaction time were examined. Linkage analysis of the corresponding alditol acetates by GC/MS allowed for calculation of average structural elements of oligomers.
