Azide- and alkynyl-containing homo-β3-peptides, of up to six residues in length, were synthesised in solution from aspartic acid. Their subsequent conjugation with monosaccharides bearing an azide or a terminal alkyne function was efficiently achieved by copper-mediated cycloadditions leading to two novel families of small glycoclusters. These compounds represent ideal tools to explore carbohydrate-mediated multivalent interactions.
以天冬氨酸为原料,在溶液中合成了长度达六个残基的含叠氮和炔基的同δ3-肽。随后,通过铜介导的环化反应,这些肽与带有叠氮或末端炔功能的单糖有效地结合在一起,形成了两个新型的小型糖簇家族。这些化合物是探索碳水化合物介导的多价相互作用的理想工具。
