selectively cleavable anchor that are stable under basic conditions are required in order that carbohydrates can be employed as chiral polyfunctional scaffolds in combinatorial solid-phase syntheses of high diversity. The schematic representation shows the combinatorial synthesis with a carbohydrate scaffold (SG=protecting group, A=anchor, P=polymer carrier), which proceeds by sequential selective deprotection
需要四个在碱性条件下稳定的正交稳定的保护基和一个可选择性裂解的锚,以使
碳水化合物可用作高多样性组合固相合成中的手性多官能支架。示意图显示了与
碳水化合物支架(SG =保护基,A =锚,P =聚合物载体)的组合合成,该合成通过依次选择性脱保护,官能化,固相洗涤和锚定物裂解进行。
