  Sulfoform generation from an orthogonally protected disaccharide

  摘要：

  An orthogonally protected disaccharide (GlcN(alpha 1 -> 4)Glc) with a beta-linked 2 '-aminoethyl linker was used to generate a series of sulfated derivatives (sulfoforms), with a 6-O-sulfate on the glucose residue and one or more sulfate esters on the terminal glucosamine. Deprotection and sulfonation steps were performed in solution and in variable order, with isolated yields of 36-54% (85-90% per operation) after HPLC purification. The modular deprotection-sulfonation sequences can be performed with efficient recovery of the polysulfate products, and avoids complications associated with heterogeneous reactivity in solid-phase synthesis.
