  • Molecular recognition of upper rim functionalized cavitand and its unique dimeric capsule in the solid state
    作者:Mutsumi Kobayashi、Mei Takatsuka、Ryo Sekiya、Takeharu Haino
    DOI:10.1039/c4ob02251c
    日期:——
    calculations revealed that the four 2,2′-bipyridyl pillars of cavitand 1 created a steric boundary that is responsible for selective guest recognition. In the solid state, cavitand 2 formed a unique chiral capsule 22 by π–π stacking interactions between the 2,2′-bipyridyl pillars. A nitromethane molecule was unusually placed deep inside the cavity, as directed by the multiple hydrogen bonding interactions
    Cavitand 1在其上缘具有四个2,2'-联吡啶基柱,这些柱将小的客体(如硝基甲烷乙腈乙酸甲酯乙酸乙酯和N-甲基酰胺)封装到一个深腔中,从而在1中形成主体-客体复合物:1的比例。硝基乙烷,N,N-二甲基酰胺和N,N-二甲基酰胺没有以这种方式结合。来宾绑定研究和分子力学计算表明,cavitand 1的四个2,2'-联吡啶基支柱形成了一个空间边界,该边界负责选择性地识别来宾。在固态下,cavitand 2形成了独特的手性胶囊2 2通过2,2'-联吡啶基柱之间的π-π堆积相互作用。根据硝基甲烷原子,桥亚甲基的C–H键和支柱基之间的多个键相互作用,将硝基甲烷分子异常地置于腔体深处。
  • Thermodynamic aspects of the host–guest chemistry of pyrogallol[4]arenes and peralkylated ammonium cations
    作者:Bjoern Schnatwinkel、Mikhail V. Rekharsky、Ralf Brodbeck、Victor V. Borovkov、Yoshihisa Inoue、Jochen Mattay

    日期:2009.3
    standard free energy (ΔGo), enthalpy (ΔHo), and entropy changes (ΔSo) for the complexation of pyrogallol[4]arenes with ammonium cations of different size and shape have been determined in ethanol at 298 K by isothermal titration calorimetry. The trends observed in the thermodynamic parameters for 1:1 and/or 1:2 host–guest complexation correspond to the systematic structural changes of the guest molecules

  • Assembly-driven synthesis of hybrid molecular capsules controlled by chiral sorting
    作者:Michał Wierzbicki、Agnieszka Szumna
    DOI:10.1039/c3cc41515e
    日期:——
    Chiral capsules with polar interiors (reversed capsules) undergo heterochiral sorting and exhibit positive mutalism – both hemispheres mutually benefit from the association. This feature can be coupled with partial reversibility of the formation reaction and utilized to amplify synthesis of hybrid capsules made of hemispheres that cannot be formed independently.

  • Cyclochiral conformers of resorcin[4]arenes stabilized by hydrogen bonds
    作者:Agnieszka Szumna
    DOI:10.1039/b701451a
    日期:——
    Cyclochiral resorcinarenes, that maintain their cyclochirality by means of hydrogen bonds, were synthesized by a sequence of reactions involving the Mannich reaction, removal of the N,O-acetal bridge and subsequent N-substitution with an RCO group. During this study it was found that ethyl nitroacetate is a mild and very efficient agent for N,O-acetal bridge removal. The resulting resorcinarenes 4a–j exist in cyclochiral/inherently chiral kite conformations (resembling 4-bladed propellers) that are stabilized by eight hydrogen bonds (in both solid state and solution). It is shown that the cycloisomerization process is characterized by the relatively high racemization barrier (14.6–18.5 kcal mol−1 as determined by 2D EXSY) and thus it can be concluded that the transformation of one cycloconformer into the other requires the simultaneous rupture of all eight hydrogen bonds. For derivatives with additional stereogenic centers two cyclodiastereoisomeric conformations were detected (diastereomeric excess in the range of 72% up to >95%). The experimental results are additionally supported by AM1 semi-empirical calculations.
    通过涉及Mannich反应、去除N,O-缩醛桥以及随后用RCO基团进行N取代的一系列反应,合成了通过键维持其环手性的环手性醚。研究中发现乙基硝基乙酸是去除N,O-缩醛桥的温和且非常有效的试剂。所得的醚4a–j存在于环手性/内在手性风筝构象中(类似于四叶螺旋桨),由八个键稳定(在固态和溶液中均是如此)。结果表明,环异构化过程的特征是相对较高的消旋化能垒(根据2D EXSY测得为14.6–18.5 kcal mol−1),因此可以得出结论,将一个环构象转变为另一个环构象需要同时断裂所有八个键。对于带有额外立体中心的衍生物,检测到了两种环二对映体构象(对映体过量范围为72%至>95%)。实验结果还得到了AM1半经验计算的支持。
  • A Chiral “Frozen” Hydrogen Bonding inC4-Symmetric Inherently Chiral Resorcin[4]arenes: NMR, X-ray, Circular Dichroism, and Theoretical Study
    作者:Bogumił Kuberski、Magdalena Pecul、Agnieszka Szumna
    DOI:10.1002/ejoc.200800247
    日期:2008.6
    substituted resorcinarenes exhibit considerable diastereomeric excesses for the induced conformational inherent chirality (up to ≥95 %). The relatively slow exchange allowed the determination of the directions of the hydrogen bond ring closures through the combined application of NMR (ROESY) and X-ray analysis. It was also possible to correlate the absolute conformation with the sign of the Cotton effects
    通过改进的曼尼希反应和随后的 N-取代反应合成了手性 C4 对称间苯二酚,在上缘被 l-氨基酸生物取代。这种类型的化合物 (5a-e) 可以两种相对稳定的固有手性 C4 对称构象 (M) 和 (P) 存在,通过形成键接缝而稳定。然而,由于非对映体的偏好,氨基酸取代的间苯二酚表现出相当多的非对映体过量,用于诱导构象固有手性(高达 ≥ 95 %)。相对缓慢的交换允许通过 NMR (ROESY) 和 X 射线分析的组合应用来确定键闭环的方向。还可以将绝对构象与在 CD 光谱(溶液和固态)中间苯二酚发色团内的跃迁观察到的棉花效应的符号相关联。模型化合物的 ab initio 计算(TDDFT/B3LYP/DZVP 和 TDDFT/CAMB3LYP/6-31++G*)表明,间苯二酚键的手性排列可以产生显着的 CD 效应,这些效应被激子耦合放大。然而,也表明相邻的酰胺基对电跃迁偶极子
