摘要：
A nickel(0)-catalyzed asymmetric [2+2+2] cocyclization has been realized for the first time. That involves conceptually new enantiotopic group selective formation of the nickelacyclopentadiene (18) and produces the isoindoline (26a) (73% ee, 78% conv. yield) and isoquinoline (27b) (54% ee, 62% yield) having benzylic chiral carbon centers.
