  A multivalent approach to the discovery of long-acting β2-adrenoceptor agonists for the treatment of asthma and COPD

  摘要：

  A multivalent approach was applied to the design of long-acting inhaled beta(2)-adrenoceptor agonists. A series of dimeric arylethanolamines based on the short acting beta(2)-adrenoceptor agonist albuterol were prepared, varying the nature and length of the linker between the basic nitrogens. None of the C-2-symmetric dimers demonstrated increased potency, however dimer 5j, derived from 4-phenethylamine, was found to have increased binding Potency in vitro relative to the parent monomer. Optimization of this structure led to the identification of 22 (milveterol) which demonstrates high potency in vitro and long duration of action in a guinea pig model of bronchoprotection.

• Highly efficient iron phthalocyanine catalyzed oxidative synthesis of imines from alcohols and amines

  日期：2013.8

  An efficient iron phthalocyanine catalyzed method was developed for direct oxidative coupling of alcohols with amines to afford corresponding imines. The present protocol is applicable to various substituted aromatic and aliphatic alcohols and amines. The reaction is believed to proceed via activation of alcohols by iron phthalocyanines through Lewis acid–base interaction to form aldehydes, which by nucleophilic attack of amines are converted into the corresponding imines.

  work, bio-based tyramine was exploited to prepare a novel phthalonitrile monomer (L-CN) with amorphous characteristics, sub-zero softening point (−16 °C) and high curing reactivity. Compared with the control compounds, it showed that amorphous structure and low softening point of L-CN cannot be simply attributed to the introduction of flexible aliphatic chain. It is proposed that the inhibited crystallization

  在这项工作中，利用生物基酪胺制备了一种新型邻苯二甲腈单体 (L-CN)，该单体具有无定形特征、低于零的软化点 (-16 °C) 和高固化反应性。与对照化合物相比，表明L-CN的无定形结构和低软化点不能简单地归因于柔性脂肪链的引入。1 HNMR、原位 FTIR 和分子动力学模拟表明，可以通过多竞争性超分子相互作用来理解 PN 单体的结晶受抑制。此外，由于脂肪胺的强亲核性和流动性，固化树脂在相对较低的后固化温度下表现出优异的热和热机械性能。

• N-Benzylazacyclophane synthesis via aromatic Mannich reaction
  作者：Christian Díaz-Oviedo、Rodolfo Quevedo

  日期：2014.11

  A new method for synthesizing phenolic N-benzylazacyclophanes starting from tyramine is presented here. Computational calculations showed that macrocyclization is favored by the formation of hydrogen bond-based templates; these templates are not affected by including benzyl groups in the nitrogen atom of the tyramine moiety. The results showed that N-benzyl groups with electron-donating substituents have more nucleophilic nitrogen atoms, thereby favoring macrocyclization, while electron-withdrawing groups favor polymerization.
