A facile synthetic approach for the synthesis of 1,8-naphthyridine-4(1H)-one derivatives via a catalyst free and Pd-supported tandem amination sequence is developed and described. In a case of aliphatic amines reaction proceeds in a catalyst free mode, however anilines demand Pd-supported reaction conditions.
开发并描述了一种简便的合成方法,通过无催化剂和钯支持的串联胺化反应合成1,8-萘啶-4(1H)-酮衍生物。在脂肪胺的反应中,无催化剂条件下进行,而芳香胺则需要钯支持的反应条件。
