The preparation of 16 macrocycles based on 2-(2-hydroxyethoxy) phenol with both aliphatic and aromatic linkers has been achieved. Macrocycles varying in ring sizes (23–28 atoms), number of aromatic groups (2–4), and donor atoms (6–10 including oxygen and nitrogen) were synthesized. Binding affinities were also assessed by extraction studies against a series of metal picrates. X-ray crystal structures were solved for four macrocycles.
以 2-(2-羟乙氧基)苯酚为基础,通过脂肪族和芳香族连接体,制备了 16 个大环。合成的大环在环的大小(23-28 个原子)、芳香基团的数量(2-4 个)和供体原子(6-10 个,包括氧和氮)方面各不相同。还通过萃取研究评估了与一系列金属苦味酸盐的结合亲和力。对四种大环的 X 射线晶体结构进行了解析。
