Polyaminopolycarboxylic acids are a well known class of ligands employed for metal ion complexation. Despite the large commercial availability, reports of their use as substrates for direct structural modifications are rare. Herein we report a simple and efficient protocol for the preparation of substituted polyaminopolycarboxylic ligands relying on a one-pot N-alkylation–Stevens rearrangement cascade.
聚氨基聚羧酸是用于金属离子络合的众所周知的一类配体。尽管商业可用性很大,但将其用作直接结构修饰底物的报道却很少。在此,我们报告了一种简单有效的方案,用于依靠一锅 N-烷基化-史蒂文斯重排级联制备取代的聚氨基多羧酸配体。
