葫芦脲 (CB) 是一种坚固且用途广泛的大环化合物,通常用作复杂超分子系统中的分子主体。在之前的工作中,在非常温和的条件下观察到不对称环加成的显着催化活性。在此,我们使用 DFT 计算和 QM/MM 技术研究超分子催化的性质。我们使用 QM/MM 模拟技术讨论了诱导构象变化、高极性水环境的静电屏蔽效应以及基质在显性水中氢键的协同作用。我们的结果显示所选分子几乎没有特异性,这表明这是扩大这些超分子大环容器催化用途范围的绝佳机会。
Cucurbiturils (CBs) are robust and versatile macrocyclic compounds, often used as molecular hosts in complex supramolecular systems. In previous work, remarkable catalytic activity has been observed for asymmetric cycloadditions under very mild conditions. Herein, we investigate the nature of supramolecular catalysis using DFT calculations and QM/MM techniques. We discuss induced conformational changes, electrostatic shielding effects from the highly polar aqueous environment and cooperativity in hydrogen bonding of the substrates in explicit water using QM/MM simulation techniques. Our results show little specificity for the chosen molecules, suggesting an excellent opportunity to expand the scope for catalytic use of these supramolecular macrocyclic containers.
