  Synthesis of Sulfonamide-Bridged Glycomimetics

  摘要：

  A flexible and short synthesis of sulfonamide-bridged di-, tri-, tetra-, and octasaccharide glycomimetics was accomplished by reaction of glycosyl thioacetates with amino sugar substrates. The chemistry to incorporate the sulfonamide linker in place of a native O-glycosidic bond was broadly scoped, allowing access to head-to-head (1 <-> 1) and head-to-tail (1 -> 2), (1 -> 3), (1 -> 4), and (1 -> 6) sulfonamide-bridged glycomimetics. The synthesis proceeds with retention of configuration at the anomeric center and is compatible with variable stereochemical arrangements and with acid- and base-labile protecting groups.
