  1,2,3,4-Tetrahydro-1,5-naphthyridines and related heterocyclic scaffolds: exploration of suitable chemistry for library development

  摘要：

  The chemistry of 1,2,3,4-tetrahydro-1,5-naphthyridines and 2,3,4,5-tetrahydro-1H-pyrido[3,2-b] azepines has been explored with the goal of discovering reactions at N1 suitable for library development. Epoxide openings, Pd-catalyzed N-arylations, DEPBT-promoted acylations, and urea formation through the reaction with isocyanates were all successful. The epoxide opening chemistry using homochiral epichlorohydrin followed by epoxide reclosure and a second nucleophilic opening led to the preparation of a small 24-membered library.

  咪唑与1,2,4-三嗪的分子内电子逆需求Diels-Alder反应：通往1,2,3,4-四氢-1,5-萘啶和相关杂环的新途径

  摘要：

  咪唑和1,2,4-三嗪之间的分子内逆电子需求的Diels-Alder反应由三亚甲基系链从咪唑N1位置连接到三嗪C3，从而以极好的收率进行生产1,2,3,4-四氢-1，5-萘啶。该反应通过环加成反应进行，随后损失氮气，然后逐步损失腈。使用四亚甲基系链的类似分子内环加成反应也以可接受的收率得到了2,3,4,5-四氢-1 H-吡啶并[3,2- b ]氮杂。微波辐射也可以促进产生四氢-1，5-萘啶的反应。

  yThe synthesis of a complex hybrid oxime library is reported utilizing convergent ligation of alkoxyamine and carbonyl monomers via "chemical domain shuffling". Initial biological screening of the library against human small cell lung carcinoma (A549) cells led to the identification of a novel hybrid dimer in contrast to the corresponding monomeric compounds which were found to be inactive.

  The intramolecular inverse-electron-demand Diels−Alder reaction between imidazoles and 1,2,4-triazines linked by a trimethylene tether from the imidazole N1 position to the triazine C3 proceed in excellent yields to produce 1,2,3,4-tetrahydro-1,5-naphthyridines. The reaction proceeds by a cycloaddition with subsequent loss of nitrogen, followed by a presumed stepwise loss of a nitrile. The analogous
