functionalization at C3/C6 of imidazo[1,2-a]pyrazines has been developed via a palladium-catalyzed sequential Suzuki–Miyaura cross-coupling/direct C–H arylation, vinylation, and benzylation. The procedure remains effective in the presence of a methyl thioether group at C8, which may in turn be successfully engaged in a cross-coupling method to afford 3,6,8-trisubstituted imidazo[1,2-a]pyrazines.

通过钯催化的连续Suzuki-Miyaura交叉偶联/直接C-H芳基化,乙烯基化和苄基化,已经开发出了咪唑并[1,2- a ]吡嗪在C3 / C6处有效的“一锅”选择性功能化。该过程在C 8处存在甲基硫醚基的情况下仍然有效,该甲基硫醚基可以依次成功地以交叉偶联方法得到3,6,8-三取代的咪唑并[1,2- a ]吡嗪。这项工作为咪唑并[1,2- a ]吡嗪系列生物相关化合物的设计铺平了道路。
