temperature without any catalyst. Moreover, both types of products can be obtained in one pot from commercial materials as well as at a gram scale. It is worthy of note that the regioselectivity of the β‐enaminones is inaccessible by the standard literature methods and their utility has been exemplified in the synthesis of diverse heterocycles. We have made every endeavor to put forward the corresponding
当务之急是学习新的合成转化方法,以成功地进行药物发现和开发。我们报告了β-烯胺酮和N的底物驱动合成来自吲哚嗪和亚硝基芳烃的芳基吡咯; 芳基取代的吲哚嗪以区域和非对映选择性的方式生成β-烯胺,而烷基取代的吲哚嗪则产生四取代的吡咯。所有产品均包含吡啶单元,这是FDA橙皮书中第二个最丰富的环(仅次于苯基)。在两种情况下,反应均在室温下进行,无需任何催化剂。而且,两种类型的产品都可以在一个锅中从商业原料以及以克为单位获得。值得注意的是,标准文献方法无法获得β-烯胺酮的区域选择性,其效用已在各种杂环的合成中得到了例证。在充分的实验工作基础上,我们已竭尽全力提出相应的反应机理。
