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.
本发明涉及用于将分子系于固体支撑物上的多功能连接剂,例如,用于将单体、寡聚物或聚合物系于固体支撑物上,这些连接剂在广泛的反应条件下稳定,但可以在明确定义的条件下被切断,从而将分子从固体支撑物中释放出来。最好的情况下,这些连接剂被用于将未保护、部分保护或完全保护的
单糖或
寡糖,或未保护、部分保护或完全保护的糖蛋白系于固体支撑物上。本发明的连接剂可用于将对于组装其他类型小分子库有用的构建块系于固体支撑物上。本发明还涉及通过本发明的连接剂将分子或多个分子系于固体支撑物上。本发明还涉及在固体支撑物上合成分子,例如单体、寡聚物或聚合物的过程,其中在合成分子的过程中,用于合成分子的起始物质、合成分子的中间体以及分子本身通过本发明的连接剂之一系于固体支撑物上。在本发明的某些过程中,通过切断本发明的连接剂将分子从固体支撑物中释放出来。
