Chiral monoaza-15-crown-5 lariat ethers attached to a 1,2-O-isopropylidene-α-d-glucofuranoside unit (10–13), monoaza-16-crown-5 lariat ethers fused to 1,2-O-isopropylidene-α-d-glucofuranoside- (18) and to 1,2-O-isopropylidene-α-d-xylofuranoside units (23 and 24) have been synthesized. The alkali metal- and ammonium picrate extracting ability of these macrocycles was investigated in dichloromethane–water
手性 monoaza-15-crown-5 套索醚连接到 1,2-O-isopropylidene-α-d-glucofuranoside 单元 (10–13),monoaza-16-crown-5套索套索醚与 1,2-O-融合已经合成了异亚丙基-α-d-呋喃葡萄糖苷-(18) 和 1,2-O-异亚丙基-α-d-呋喃木糖苷单元 (23 和 24)。在二氯甲烷-水系统中研究了这些大环化合物的碱金属和苦味酸铵萃取能力。一般来说,对于几乎所有的阳离子,15 元大环化合物(10-13)比 16 元套索醚(18、23 和 24)具有更显着的萃取能力。以α-d-呋喃葡萄糖苷为基础的三苯甲基(三苯甲基)醚衍生物(18)制备增塑PVC膜电极(ISE),并用分段夹心膜法测定其电位选择性和络合物形成常数。此外,还通过竞争性 ESI-MS 实验测量了离子载体对不同金属离子的结合亲和力。其中一种基于 1,2-O-异亚丙基-α-d-呋喃葡萄糖苷的套索醚
