  Thioglycuronides:  Synthesis and Application in the Assembly of Acidic Oligosaccharides

  摘要：

  Partially protected thioglycuronic acids are prepared efficiently by chemo- and regioselective oxidation of the corresponding thioglycosides using the TEMPO/BAIB reagent combination. After esterification, the thioglycuronic acids proved to be useful as both donor and acceptor in sulfonium-mediated condensations toward acidic di- and trisaccharides.

  Well-defined fragments of hyaluronic acid (HA) have been obtained through a fully automated solid-phase oligosaccharide synthesis. Disaccharide building blocks, featuring a disarmed glucuronic acid donor moiety and a di-tert-butylsilylidene-protected glucosamine part, were used in the rapid and efficient assembly of HA fragments up to the pentadecamer level, equipped with a conjugation-ready anomeric

  The synthesis of hyaluronan dimers and tetramers equipped with a 4-methylumbelliferyl group at the reducing end to potentially allow monitoring of hyaluronidase activities is described. The 4-OH at the non-reducing glucuronate in the presented series is either removed or methylated to prohibit transglycosylase reactions, leading to a total of four probes. (C) 2011 Elsevier Ltd.

  日期：2009.6.5

  An efficient synthetic strategy toward a hyaluronic acid (HA) tri-, penta-, and heptamer having a glucosamine-reducing end is reported. The synthesis is based on a glucuronate ester thioglycoside and a trifluoro-N-phenylimidate glucosamine building block. The HA-fragments are synthesized using an S-phenyl GlcN-GluA building block through a combination of chemoselective and one-pot condensation strategies.
