  亚甲基桥甘脲二聚体：合成方法。

  摘要：

  亚甲基桥甘脲二聚体是葫芦素（CB [6]），其同系物（CB [n]）及其衍生物的基本组成部分。本文介绍了三种互补的合成C型和S型亚甲基桥甘脲二聚体的方法（29-34和37-44）。为此，我们制备了在其凸面上具有多种功能的甘脲衍生物（1a-d）。这些甘脲衍生物在碱性条件下（DMSO，t-BuOK）用1,2-双（卤甲基）芳烃6-15烷基化，得到4a-d和16-24，其中含有一个芳族邻二甲苯基环并可能具有亲核性脲基NH基团。带有潜在亲电环醚基团（5a-f）和25-28的甘脲衍生物是通过各种方法制备的，包括在回流的含多聚甲醛的TFA中进行缩合反应。在大多数情况下，在无水酸性条件下（PTSA，ClCH（2）CH（2）Cl，回流），4a-d和16-24与低聚甲醛的缩合反应可得到C形和S形亚甲基桥接的甘脲高产到高产。在许多情况下，优选以高非对映选择性形成C形化合物。环醚5a，df和25-26经历高度非对

  possible previously. For example, we present strong evidence that the mechanism of CB[n] synthesis proceeds via the intermediacy of both S-shaped and C-shaped dimers. The first experimental determination of the relative free energies of the S-shaped and C-shaped dimers indicates a thermodynamic preference (1.55-3.25 kcal mol(-)(1)) for the C-shaped diastereomer. This thermodynamic preference is not because

  Cucurbit[6]uril (CB[6]) 是一种大环化合物，由甘脲和甲醛在一锅中制备，其分子识别特性使其成为深入研究的对象。CB[n] 形成机制的研究可能为 CB[n] 同系物和衍生物的定制合成提供见解，但由于 CB[n] 的复杂结构而受到阻碍。通过降低形成 S 形 (12S-18S) 和 C 形 (12C-18C) 亚甲基桥联甘脲二聚体的反应复杂性，我们已经能够探索 CB[n] 机制的基本步骤合成到以前不可能达到的水平。例如，我们提出了强有力的证据，证明 CB[n] 合成的机制是通过 S 形和 C 形二聚体的中介进行的。S 形和 C 形二聚体的相对自由能的第一次实验测定表明 C 形非对映异构体的热力学偏好 (1.55-3.25 kcal mol(-)(1))。这种热力学偏好不是因为自缔合、溶剂化或模板效应。此外，标记实验使我们能够阐明 S 形和 C 形非对映异构体之间这种酸催化平衡

  The acid-catalyzed formation of methylene-bridged glycoluril dimers yields the C-2v-diastereomer selectively. Product resubmission experiments establish that the selectivity is the result of thermodynamic control. A modified synthetic route is presented that allows for the preparation of unsymmetrically substituted dimers, We present the X-ray crystal structures of both diastereomers, This class of compounds is useful for studies of self-assembly in aqueous solution.

  Experimental details are given for the synthesis and characterization of several new molecules capable of self-assembly. The new molecules feature glycoluril subunits held apart by various rigid spacers, ethylene (2), naphthalene (3), and ethenoanthracene (4), and assemble through hydrogen bonds into pseudo-spherical dimeric capsules. The nature of their assembly is demonstrated by the X-ray crystal structure of capsules 1.1. The capsules are shown to enclose smaller guest molecules in a reversible manner. Direct evidence of the guest molecules inside the capsules from NMR is presented. In addition to self-assembling dimerically, these new molecules are shown to disproportionate into hybrid species or heterodimers. The resulting new capsules feature internal cavities of varying sizes and shapes. Formation of hybrid dimers 1.2, 1.4, and 3.4 is observed in solutions containing mixtures of two homodimers. The dispropoaionation equilibria could be manipulated by the addition of appropriately sized solvents as guests. Even the energetically unlikely hybrids 1.4 and 3.4 are found to be the dominant species when suitable guests such as CDBr3 are present. Evidence of the existence of the heterodimers is presented from NOE measurements. Factors controlling the heterodimerization are discussed.
