    give the respective resorcin[4]‐ or pyrogallol[4]arenes. The preorganization of the phenolic units allows intra‐ and intermolecular hydrogen bond (HB) networks that affect both the reactivity and stability of these HB‐donor catalysts. Unexpectedly, we found that the resorcin[4]arenes show cooperative catalysis behavior compared to the parent resorcinol in the catalytic coupling of epoxides and CO2

Most of the resulting resorcinareneamides are thus obtained in preparative yields and can be easily purified by simple crystallizations.

  • Conformational polymorphism and amphiphilic properties of resorcinarene octapodands
    作者:Kaisa Helttunen、Elisa Nauha、Anni Kurronen、Patrick Shahgaldian、Maija Nissinen
    DOI:10.1039/c0ob00602e
    日期:——
    o-Nitroaniline functionalized resorcinarene octapodands 1–5 with pendant methyl, ethyl, pentyl, nonyl or 1-decenyl groups, respectively, were synthesized and their structural properties investigated using X-ray crystallography and NMR spectroscopy. The upper rim of each podand is identical containing flexible side arms, in which rotation around the -OCH2CH2N- linkers create excellent possibilities for polymorphism. Two conformational polymorphs of acetone solvate of 2 were identified containing different side arm orientation and crystal packing. Compound 1 crystallized from acetone and nitromethane yielding two pseudopolymorphs with different packing motifs. The longer alkyl chains of 3–5 lead to differences in solubility and induce amphiphilic properties, which were studied at the air–water interface using the Langmuir-film technique. Crystals of amphiphilic compound 5, which has hydrophobic alkyl tails at the lower rim and hydrophilic nitroaniline groups at the upper rim, showed an interesting packing motif with alternating aromatic and aliphatic layers. Versatile structures of the octapodands in solid state and in solution serve as an example of how conformational flexibility can be utilized in crystal engineering and creating self-assembling monolayer structures.

  • 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,合成了通过氢键维持其环手性的环手性醚。研究中发现乙基硝基乙酸酯是去除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),由八个氢键稳定(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氢键。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。
