An acid catalysed ring rearrangement of a triflate derivative of D-mannono-?-lactone 6 is the key step in the synthesis of the C-glycosyl sugar amino acid derivatives 3 and 4, examples of carbohydrate amino acid building blocks with specific conformational preferences suitable for incorporation into combinatorial amide libraries; homo-oligomerisation via solution phase coupling procedures affords furanose carbopeptoids 1 which adopt novel solution state secondary structures.
D-甘露醇-β-内酯 6 的三氟甲磺酸酯衍生物的酸催化环重排是合成 C-糖基糖氨基酸衍生物 3 和 4 的关键步骤,它们是具有特定构象偏好的碳水化合物氨基酸结构单元的例子,适合用于并入组合酰胺文库;通过溶液相偶联程序进行同源寡聚,得到呋喃糖碳肽 1,其采用新颖的溶液态二级结构。
