  Synthesis of Oligopyridinic Scaffolds from Amido Substituted Phenyl Rings for Extended Hydrogen Bonding

  摘要：

  一系列结合了4-甲基-3,5-双酰胺苯基平台和两个二烷氧基苯基的菲咯啉、三吡啶和喹啉-噁唑啉配体通过线性多步方法制备。通过在单步反应中构建配位片段，评估了4-甲基-3,5-(双酰胺二烷氧基苯基)苯甲酸的合成潜力。这些氮基团的接枝是通过在温和条件下使用EDC·HCl和DMAP试剂实现的。本文报告的合成方法提供了一种实用的途径，以合理设计具有各种功能的配体，如酯键、酰胺键以及石蜡链。这种方法的一个显著优点是它允许在合成方法的末端将4-甲基-3,5-双酰胺苯基平台引入到寡吡啶框架中。

• Tuning Organogels and Mesophases with Phenanthroline Ligands and Their Copper Complexes by Inter- to Intramolecular Hydrogen Bonds

  Heating the complexes bearing long paraffin chains (n = 12 and 16) in the dried state leads to a self-organization into a columnar liquid-crystalline phase in which the columns are arranged along a 2D oblique symmetry as deduced from powder XRD experiments. In this case, the complexes with the appended counteranions self-assemble in a specific way to form columns. A striking observation is that the intramolecular

  We report on the synthesis and self-assembly of a new series of discotic molecules containing triphenylbenzene as the core and alkoxy side chain with varying length. It was found that compounds 3 a-c, 4 b and 5 b could form stable gels in several apolar solvents. Transmission electron microscopy (TEM) images revealed that their morphologies were very different for the different alkoxy-substituted organogels

  我们报道了一系列新的盘状分子的合成和自组装，这些盘状分子以三苯苯为核心和长度可变的烷氧基侧链。发现化合物3ac，4b和5b可以在几种非极性溶剂中形成稳定的凝胶。透射电子显微镜（TEM）图像显示，对于不同的烷氧基取代的有机凝胶，它们的形态非常不同。在甲苯或己烷中，3 b和3 c产生左旋和右旋螺旋纤维，而3 a产生直的硬质纤维。图4b和5b显示出大多数的直纤维和少量的扭曲纤维。FT-IR和UV / Vis吸收光谱的结果表明，氢键和pi-pi相互作用是自组装凝胶形成的主要驱动力。通过紫外可见吸收光谱和X射线衍射（XRD）测量对它们的聚集模式进行了更详细的分析。基于这些发现，讨论了这些外围烷氧基取代基对凝胶形成和聚集模式的影响。在凝胶相中还发现了由于聚集而引起的特殊增强的荧光发射。
• A Convenient Protocol for the Synthesis of Ligands from a 4-Methyl-3,5-diacylaminophenyl Platform

  The synthesis of stable and highly organized phenanthroline, terpyridine, and pyridino-oxazoline ligands bearing one or two 4-methyl-3,5-diacylaminophenyl modules equipped with two lateral dialkoxyphenyl groups has been performed using EDC.HCl and DMAP reagents in the final coupling reaction. Evidently, in the final ligands and in the solid state intermolecular hydrogen bonding maintains the coherence of the tridimensional structure as clearly evidenced by FT-IR and X-ray diffraction spectroscopy in the cases of the methoxy ligands. The supramolecular packing is also maintained by additional pi-pi stacking interactions.

  Metastatic bone disease is often associated with bone pain, pathologic fractures, and nerve compression syndromes. Effective therapies to inhibit the progression of bone metastases would have important clinical benefits. Therefore, we developed a novel calcium phosphate-binding liposome for a bone-targeting drug delivery system. We synthesized a novel amphipathic molecule bearing a bisphosphonate (BP) head group to recognize and bind to hydroxyapatite (HA). We demonstrated that the liposomes having BP moieties show high affinity for HA. Doxorubicin-loaded liposomes adsorbed on the surface of HA significantly reduce the number of viable human osteosarcoma MG63 cells. This shows that the liposomes can be excellent carriers for anticancer drugs because they specifically target bone tissue. This calcium phosphate-binding liposome system could be used with many drugs for bone-related diseases such as osteoporosis, rheumatoid arthritis, and multiple myeloma. (C) 2009 Elsevier Ltd.

  日期：——

  A series of phenanthroline, terpyridine and pyridino-oxazoline ligands combining a 4-methyl-3,5-diacylaminophenyl platform and two dialkoxyphenyl groups has been prepared by a linear multistep protocol. The synthetic potential of 4-methyl-3,5-(diacyl­aminodialkoxyphenyl)benzoic acids was assessed by the construction, in a single step, of the chelating fragments. The grafting of these nitrogen-based groups is realized by the use of EDC·HCl and DMAP reagents under mild conditions. The synthetic methods reported herein provide a practical approach to the rational design of ligands bearing various kinds of functionalities such as the ester and amido linkages as well as the paraffin chains. A significant merit of this method is that it allows the introduction of the 4-methyl-3,5-diacylaminophenyl platform onto the oligopyridinic framework at the end of the synthetic protocol.
