Ir(I)-Catalyzed Enantioselective Secondary sp3 C–H Bond Activation of 2-(Alkylamino)pyridines with Alkenes
摘要:
A cationic Ir(1)-tolBINAP complex catalyzed an enantioselective C-C bond formation initiated by secondary sp(3) C-H bond cleavage adjacent to a nitrogen atom. The reaction of 2-(alkylamino)pyridines with various alkenes gave chiral amines In good yields with high enantiomeric excesses.
A cationic Ir(I)–tolBINAP complex catalyzed an enantioselective C–C bond formation, which was initiated by secondary sp3 C–H bondcleavage adjacent to nitrogen atom. A wide variety of 2-(alkylamino)pyridines and alkenes were selectively transformed into the corresponding chiral amines with moderate to almost perfect enantiomeric excesses. Alkynes were also investigated as coupling partners. The effect
