Homothiacalix[n]arenes have been largely underexposed compared with related (homo)heteracalixarenes, although their inherent structural features are particularly attractive for supramolecular host–guest chemistry. In this contribution, the synthetic macrocyclization protocols that afford homothiacalix[n]arenes have been reinvestigated and optimized, providing straightforward access to the parent h
与相关的(同)杂acalixarenes相比,homothiacalix [ n ]芳烃在很大程度上暴露不足,尽管它们的固有结构特征对于超分子宿主-客体化学特别有吸引力。在此贡献中,对提供了高硫杂杯[ n ]芳烃的合成大环化方案进行了重新研究和优化,从而可以直接访问母体高硫杂杯[4]芳烃骨架。此外,还成功进行了内缘(双和四)酯官能化和二亚甲基桥氧化反应。溶液相(可变温度)NMR光谱研究和固态X射线结构提供了有关新型大环化合物构象特征的补充信息。
