3a are reported. A convergent synthesis of the linear hexahomotrimer precursors 19 and 19a is described, but the direct synthesis of 3 and 3a can also be achieved from the monomers 20 and 20a, respectively. A limited study of the binding properties of alkali-metal cations by 3 or 3a using a picrate-CHCl3 extraction showed only weak abilities to bind with the cations examined.
据报道,分别合成了C3-对称和不对称的六高三氧杂lix [3]萘3和4,以及相应的叔丁基六高三氧杂lix [3]萘3a。描述了线性六均三聚体前体19和19a的会聚合成,但是3和3a的直接合成也可以分别由单体20和20a实现。使用苦味酸盐-CHCl3萃取对3或3a的碱金属阳离子的结合特性进行的有限研究表明,与被检测的阳离子结合的能力很弱。
