  Synthesis of disaccharidic sub-units of a new series of heparin related oligosaccharides

  摘要：

  The chemical synthesis of disaccharides 1 and 2, useful building-blocks for the preparation of a new series of heparin related oligosaccharides containing the unusual sequence (GlcN-IdoA)(n), is described. In addition, the orthogonality of the protective groups would allow access to a wide array of differently sulfated oligosaccharides. As the simplest members of this new class of oligomer, the synthesis of sulfated disaccharides 3 and 4 fully deprotected is reported. (C) 1999 Elsevier Science Ltd. All rights reserved.

  O-[Methyl (2-O-acetyl-3-O-benzyl-4-O-levulinyl-alpha, and beta-L-idopyranosid)uronate] trichloroacetimidate and the corresponding n-pentenyl glycosides are efficient L-iduronic acid glycosyl donors. Both have been used for the high-yielding synthesis of basic disaccharide blocks which are useful for the subsequent synthesis of complex oligosaccharides related to heparin/heparan sulfate, and dermatan

• One-Step TEMPO-Catalyzed and Water-Mediated Stereoselective Conversion of Glycals into 2-Azido-2-deoxysugars with a PIFA–Trimethylsilyl Azide Reagent System

  日期：2018.5.4

  An unprecedented water-mediated and TEMPO-catalyzed, one-step, highly regiospecific and stereoselective functionalization of glycals to 2-azido-2-deoxysugars has been developed using a PIFA-Me3SiN3 reagent system in the presence of Bu4NHSO4 as a phase-transfer catalyst. The method is metal-free, proceeds under mild reaction conditions, and tolerates a variety of protecting groups. Using this method, the synthesis of an important trisaccharide unit bound by the monoclonal anti-I Ma antibody has also been demonstrated.
