| 摘要 |
The present invention relates to versatile linkers for tethering a molecule to a solid support, e.g., for tethering a monomer, oligomer or polymer to a solid support, which are stable to a wide range of reaction conditions, but can be cleaved under well-defined conditions, thereby liberating the molecule from the solid support. Preferably, the linkers are used to tether to the solid support unprotected, partially-protected or fully-protected monosaccharides or oligosaccharides, or unprotected, partially-protected or fully-protected glycoconjugates. The linkers of the present invention may be used to tether to solid supports building blocks useful in the assembly of libraries of other types of small molecules. The present invention also relates to a molecule or plurality of molecules tethered to the solid support via a linker or linkers of the present invention. The present invention also relates to processes for synthesizing molecules, e.g., monomers, oligomers or polymers, on a solid support, wherein a starting material in the synthesis of the molecule, intermediates in the synthesis of the molecule, and the molecule itself are tethered to the solid support during the process via one of the linkers of the present invention. In certain processes of the present invention, the molecule is liberated from the solid support by cleavage of the linker of the present invention.
