Asymmetric Synthesis of Isoindoline and Isoquinoline Derivatives Using Nickel(0)-Catalyzed [2 + 2 + 2] Cocyclization
摘要:
A nickel(0)-catalyzed asymmetric [2 + 2 + 2] cocyclization has been realized for the first time, giving the isoindoline 16a in 73% ee (52% yield) and the isoquinoline 17b; in 54% ee (62% yield), respectively.
