A method for the combinatorial synthesis of oligosaccharides comprising the steps of: (i) conjugating a saccharide building block containing orthogonally protected functional groups to a solid support, the protection being via at least one protecting group, (ii) cleaving the or each protecting group from functional groups on the monosaccharide building block through which there will be no chain elongation and capping these functional groups with a capping moiety which comprises a protecting group or chain terminating moiety, and (iii) sequentially removing the protecting groups from the functional groups through which there is intended to be chain elongation and glycosylating with another orthogonally protected building block.
一种组合合成
寡糖的方法,包括以下步骤:(i)将含有正交保护官能团的糖基构建块与固体支持物偶联,保护是通过至少一个保护基团实现的,(ii)从
单糖基构建块上的官能团中剥离或每个保护基团,通过这些官能团不会进行链延伸,并用包含保护基团或链终止基团的封端基团封顶这些官能团,(iii)依次从将进行链延伸的官能团中去除保护基团,并用另一个正交保护的构建块进行糖基化。
