Fluorous-Tagged Carbamates for the Pd-Catalyzed Amination of Aryl Halides
摘要:
[GRAPHICS]A novel fluorous-tagged ammonia surrogate has been synthesized and its application to the synthesis of anilines by Buchwald-Hartwig palladium-catalyzed amidation-hydrolysis protocol is described. Primary anilines were obtained in moderate to good yields after a sequence of two reaction steps involving fluorous separation techniques for their purification. Preliminary results indicate that N-substituted anilines can also be obtained using just N-substituted-(F)Boc carbamates as the nitrogen source.
