Abstract p‐Toluenesulfonic acid catalyzed the one‐pot, three‐component synthesis of 3‐aminoimidazo[1,2‐a]pyridines and pyrazines through a condensation reaction of a 2‐aminoazine, an aldehyde, and an isocyanide at room temperature. This methodology affords a number of 3‐aminoimidazo[1,2‐a]pyridines in reasonable yields and short reaction times without any significant optimization of the reaction conditions
摘要 对甲苯磺酸通过 2-氨基嗪、醛和异氰化物在室温下的缩合反应催化了 3-氨基咪唑并[1,2-a]吡啶和吡嗪的一锅三组分合成。该方法以合理的产率和较短的反应时间提供了许多 3-氨基咪唑并 [1,2-a] 吡啶,而无需对反应条件进行任何显着优化。
