Rapid and Efficient Microwave-Assisted Synthesis of Aryl Aminobenzophenones Using Pd-Catalyzed Amination
摘要:
Substituted aryl aminobenzophenone p38 MAP kinase inhibitors were synthesized in good to excellent yields using palladium-catalyzed aryl amination under conditions of microwave irradiation. Various ligands have been screened, and the reaction conditions were optimized. These coupling reactions are suitable for various anilines and aryl bromides that bear a variety of functional groups. Some leaving groups (iodides, chlorides, triflates, and tosylates) other than bromides have also been investigated. By this method, a large number of aryl aminobenzophenone p38 MAP kinase inhibitors were prepared in short order.

The synthesis of a series of substituted 9H-carbazoles by the photostimulatedSRN1 substitution reaction with diarylamines as starting substrate was performed. The diarylamines were obtained by two approaches, the Pd-catalyzed reactions (Buchwald−Hartwig) or Cu-catalyzed reactions of 2-haloanilines with arylhalides, or 2-bromoiodobenzene with anilines, with moderate to very good isolated yields (45−89%)
