The syntheses of the triesters formed between ethyl bromoacetate and hexahomotrioxacalix[3]naphthalene 8, and its tert-butyl analogue 11, are described. Depending on the conditions employed, cone or partial cone conformers are produced. The conformations appear to have some influence on their complexation in neutral medium, with alkali metal cations. The X-ray structure of the partial cone triester 10 is presented.

溴乙酸乙酯和六氢三氧杂[3]
萘 8 及其叔丁基类似物 11 三酯的合成。根据所用条件的不同,会产生锥形或部分锥形构象。这些构象似乎对它们在中性介质中与碱
金属阳离子的络合有一定的影响。本文介绍了部分锥形三酯 10 的 X 射线结构。
