Fluorous-Tag Assisted Syntheses of Sulfated Keratan Sulfate Oligosaccharide Fragments.

The first block iteration strategy for iterative solution-phase synthesis of protected keratan sulfate (KS)-like fragments is reported. Obstacles in a strategy using galactose-glucosamine (Gal-GlcNAc) modules led to the discovery of a differentially protected GlcNAc-Gal module that could be used to synthesize KS-like fragments using a fluorous tag that maintained solubility in organic solvents for purification of all intermediates via fluorous solid-phase extraction.
