使用不同的合成路线选择性地制备了锥形和部分锥形构象的硝基取代杯芳烃。杯[4]芳烃或杯[6]芳烃的三或五取代苯酚的选择性硝化提供了单硝基杯[ n ]芳烃(n = 4,6)。随后将乙二醇(EG)部分添加到单硝基杯[4]芳烃中,得到呈锁定部分圆锥构象的四乙二醇基杯[4]芳烃。通过另一种方法-在未衍生化的杯[4]芳烃中首先添加EG部分,然后进行不受控制的硝化-将单硝基和二硝基四乙二醇基杯[4]芳烃锁定在锥中构象。这些具有锁定的圆锥或部分圆锥构象的硝基杯[4]芳烃是有用的构件,用于进一步组装超分子系统,特别是在材料科学领域。
with primary benzensulfonamides demonstrated their ability of inhibiting humanCarbonicAnhydrases with significant efficiency and selectivity among different isoforms of the enzymes. A mode of binding where the benzensulfonamide arm penetrates into the funnel of the enzyme active site and interacts with the protein Zn2+ ion is supported by X-ray diffraction data and MD calculations.

Molecularreceptors for organic molecules are described in which calix[4]arene is used as a molecular platform rather than for its cavity. This is illustrated by the synthesis of a receptor for barbiturates, a calix[4]arene in a cone conformation containing two diaminotriazine moieties at the upper rim. This receptor (9) forms a molecular cleft in which phenobarbital complexes by hydrogen bonding both
描述了有机分子的分子受体,其中杯[4]芳烃被用作分子平台而不是其空腔。巴比妥酸盐受体的合成,即圆锥构象的杯[4]芳烃在上边缘含有两个二氨基三嗪部分,由此说明了这一点。该受体(9)形成分子裂口,其中苯巴比妥通过氢键合两个三嗪环而形成苯巴比妥复合物。当考虑巴比妥酸盐的自缔合时,缔合常数K为520 M 1。

Calix[4]arenes in a rigid cone conformation that contain selfcomplementary alpha-pyridone moieties at the upper rim, form aggregates in CDCl3 solution, which can be denaturated by the formation of a complex with urea derivatives.
