Di-,tri- and tetrapeptide linked dicatechol derivatives are prepared by subsequent coupling of 2,3-dimethoxybenzoic acid (2), peptides 3 and 2,3-dimethoxybenzylamine (5) using classical activating conditions (EDC/HOBt or DDC/HOSu). In the final step the methyl ethers at the veratrol units are cleaved to afford the free catechol derivatives 7, which are potential ligands for metal complexes with well
使用经典活化条件(EDC/HOBt 或 DDC/HOSu)通过随后偶联 2,3-二甲氧基苯甲酸 (2)、肽 3 和 2,3-二甲氧基苄胺 (5) 来制备二肽、三肽和四肽连接的联苯二酚衍生物. 在最后一步中,藜芦醇单元上的甲基醚被裂解,得到游离的儿茶酚衍生物 7,它们是在肽间隔区具有明确固定构象的金属络合物的潜在配体。
