Palladium-Catalyzed Synthesis of Pyrrolo[1,2-α]Pyrazines From N-Phenacyl Pyrrole-2-Carbonitriles and Aryl Boronic Acids

초록

Herein, we have developed palladium-trifluoroacetate-catalyzed carbo-palladation reaction of pyrrole-2-carbonitriles and aryl boronic acids leading to functionally diverse pyrrolo[1,2-alpha]pyrazines under thoroughly optimized reaction conditions. The reaction proceeded smoothly and allowed the diversity-oriented synthesis of pyrrolo[1,2-alpha]pyrazines with broad substrate scope with respect to pyrrole-2-carbonitriles and aryl boronic acids.
