  摘要：

  The synthesis of 4,6-O-benzylidene-beta -D-erythro-2-3-dideoxyhex-2-enopyranosides and their osmium and ruthenium catalysed dihydroxylation reactions have been investigated. These reactions have been shown, for a range of monosaccharides and a disaccharide, to proceed stereospecifically to give beta -D-allopyranosides in moderate to excellent yield.

• Synthesis and NMR characterization of the six regioisomeric monophosphates of octyl β-d-galactopyranosyl-(1→4)-2-acetamido-2-deoxy-β-d-glucopyranoside

  All six regioisomeric monophosphates of octyl beta-D-galactopyranosyl-(1 --> 4)-2-acetamido-2-deoxy-beta-D-glucopyranoside have been chemically synthesized and characterized by high-resolution H-1, C-13 and P-31 NMR spectroscopy. Phosphorylation causes characteristic downfield shifts of the nucleus at the substituted site in the H-1 and C-13 NMR signals and resulted in a unique P-31 signal for each compound.
