We developed an efficient one-pot tandem carbamoyl chloride amination and palladium-catalyzed intramolecular urea cyclization, which furnished high-throughput access to imidazo[4,5-b]pyridine-2-one and related imidazo[4,5-c]pyridine-2-one ring systems. Moderate to excellent yields were reported.
我们开发了一种高效的一锅串联碳酰氯氨化和钯催化的分子内脲环化反应,为高效构建咪唑并[4,5-b]吡啶-2-酮和相关咪唑并[4,5-c]吡啶-2-酮环系提供了途径。该方法具有中等至优异的产率。
