Alkylated imidazopyridines are crucial structures for medicinal chemistry. Here, an efficient method for the C3–H alkylation of imidazopyridines was devised. Under Lewis acid-catalyzed conditions, reactions of imidazopyridines with different donor–acceptor cyclopropanes were carried out. Finally, 1,3-bisfunctionalizaton of donor–acceptor cyclopropanes was performed. In addition, synthesized C3-alkylated
烷基化咪唑并吡啶是药物化学的重要结构。在这里,设计了一种有效的咪唑并吡啶 C3-H 烷基化方法。在路易斯酸催化条件下,咪唑并吡啶与不同供体-受体环丙烷发生反应。最后,进行供体-受体环丙烷的 1,3-双官能化。此外,合成的C3-烷基化咪唑并吡啶适合多种合成应用。
