A new “cap-and-tag” strategy is applied to solidphaseoligosaccharidesynthesis. Acetyl-capping and fluorous-tagging allowed for the facile separation of the desired F-tagged oligosaccharide from the acetyl-capped deletion sequences using fluorous solidphase extraction. To illustrate this approach, a protected Glc-β-(1→6)-Man-α-(1→6)-Glc-β-1→pentenyl trisaccharide was synthesized.
