A new palladium-catalyzed method to prepare pyrroles directly from three basic building blocks-imines, alkynes, and acid chlorides-is described. This approach provides a straightforward method both to prepare pyrroles in one step and to diversify their structure by simple variation of any of the three starting materials. Mechanistic studies suggest that this process occurs via a complex series of eight
描述了一种新的钯催化方法,可直接从三种基本结构单元(亚胺、炔烃和酰氯)制备吡咯。这种方法提供了一种简单的方法,既可以一步制备吡咯,又可以通过简单改变三种起始材料中的任何一种来使其结构多样化。机理研究表明,该过程通过一系列复杂的八个单独步骤发生,对此进行了讨论。
