Solid-phase carbohydrate synthesis via on-bead protecting group chemistry

Di- and tri-saccharides were synthesized on a solid phase. The procedure started with a non-protected sugar linked via either cysteine or glutamine to a polystyrene resin. Selective dimethoxytritylation chemistry and subsequent steps yielded a resin-bound acceptor that could be glycosylated to yield β1,6-linked disaccharides. Reiteration of the procedure produced the trisaccharide.

A new strategy in oligosaccharide synthesis using lipophilic protecting groups: synthesis of a tetracosasaccharide

The use of lipophilic, acyl-type protecting groups in the synthesis of higher-membered oligosaccharides is described by the example of oligosaccharides corresponding to the O-specific polysaccharide (O-SP) of Shigella dysenteriae type 1. Thus, O-stearoyla
