  • Protecting and linking groups for organic synthesis on solid supports
    Patent number: 6765089
    Abstract: This invention relates to methods for synthesis of organic compounds, and in particular to compounds useful as protecting and linking groups for use in the synthesis of peptides, oligosaccharides, glycopeptides and glycolipids. The invention provides protecting and linking groups that are useful in both solid phase and solution synthesis, and are particularly applicable to combinatorial synthesis.

  • Oligosaccharide synthesis
    Patent number: 6723843
    Abstract: The invention provides a system for solid-phase synthesis of oligosaccharides, based on the discovery that a 2-substituted-1,3-dioxocycloalkyl linker group of general formula (I) can be used to couple saccharide groups of both the O-glycoside and N-glycoside type to a polymer support. The invention provides reagents, reagent kits and methods for solid-phase oligosaccharide synthesis.

  • Protected aminosugars
    Patent number: 6462183
    Abstract: The invention provides amine-protecting groups for use in solution phase or solid-phase oligosaccharide synthesis, in which a 2-substituted 1,3-dioxo compound is used to protect one or more primary amine groups of an aminosugar or gylycosylamine. The invention provides reagents, reagent kits, and methods for solution phase, solid-phase oligosaccharide synthesis.
