Synthesis of new types of peptidomimetics and glycosylated amino acids possessing 1,2,3-triazole and carbamate moieties is described. Poc-protected amino acid esters/1-amino sugars were subjected to Cu(I) catalyzed [2+3]cycloaddition with desired azides under click protocol to obtain novel peptide and carbohydrate mimetics. The reaction is rapid, efficient and all the products are isolated in good yield and excellent purity.
描述了新型肽类似物和具有1,2,3-三唑和氨基甲酸酯基团的糖基氨基酸的合成。经Poc保护的氨基酸酯/1-氨基糖在点击反应条件下与所需的叠氮化合物进行Cu(I)催化的[2+3]环加成反应,以获得新型的肽和碳水化合物类似物。该反应快速、高效,所有产物均以良好的产率和优异的纯度分离得到。
