  Two series of novel 4-phenoxypyridine derivatives containing imidazole-4-carboxamide and 4-methyl-5-oxo-4,5-dihydro-1,2,4-triazole-3-carboxamide moieties were synthesized and evaluated for their in vitro inhibitory activities against c-Met kinase and antiproliferative activities against MKN-45, A549 and H460 cancer cell lines. The results indicated that most of the compounds showed moderate to good

  Multicomponent polymerizations have become powerful tools for the construction of sequence-defined polymers. Although the Passerini multicomponent reaction has been widely used in the synthesis of sequence-defined polymers, the tandem usage of the Passerini multicomponent reaction and other multicomponent reactions in one-pot for the synthesis of sequence-defined polymers has not been developed until now. In this contribution, we report the tandem usage of the Passerini three-component reaction and the three-component amine-thiol-ene conjugation reaction in one pot for the synthesis of sequence-defined polymers. The Passerini reaction between methacrylic acid, adipaldehyde, and 2-isocyanobutanoate was carried out, affording a new molecule containing two alkene units. Subsequently, an amine and a thiolactone were added to the reaction system, whereupon the three-component amine-thiol-ene conjugating reaction occurred to yield a sequence-defined polymer. This method offers more rapid access to sequence-defined polymers with high molecular diversity and complexity.

  多组分聚合已成为构建序列定义聚合物的强大工具。尽管Passerini多组分反应已广泛应用于序列定义聚合物的合成，但迄今为止，在一锅中联用Passerini多组分反应和其他多组分反应来合成序列定义聚合物尚未得到发展。在此项研究中，我们报告了在一锅中联用Passerini三组分反应和三组分胺-硫醇-烯结合反应来合成序列定义聚合物。我们进行了以甲基丙烯酸、戊醛和2-异氰基丁酸酯为反应物的Passerini反应，产物为含有两个烯键单元的新分子。随后，向反应体系中加入了一种胺和一种硫内酯，随后发生了三组分胺-硫醇-烯结合反应，产生了序列定义聚合物。这种方法提供了更快速获得高分子多样性和复杂性的序列定义聚合物的途径。
