Abstract Pyrimido[4,5-b]carbazole derivatives were synthesized by a copper- or palladium-catalyzed sequential amidation and cyclization process in which a C–N bond formed at the 2-position of a 3-formylcarbazole afforded a new 9-substituted N-(3-formyl-9H-carbazol-2-yl)amide. Pyrimido[4,5-b]carbazole derivatives were synthesized by a copper- or palladium-catalyzed sequential amidation and cyclization
摘要 嘧啶[4,5- b ]咔唑衍生物是通过铜或钯催化的连续酰胺化和环化过程合成的,其中在3-甲酰基咔唑的2-位形成的C–N键提供了一个新的9-取代的N -(3-甲酰基-9 H-咔唑-2-基)酰胺。 嘧啶[4,5- b ]咔唑衍生物是通过铜或钯催化的连续酰胺化和环化过程合成的,其中在3-甲酰基咔唑的2-位形成的C–N键提供了一个新的9-取代的N -(3-甲酰基-9 H-咔唑-2-基)酰胺。
