From: Ni(II)-catalyzed asymmetric alkenylations of ketimines
Sterically-controlled site-selective asymmetric alkenylation/ring-expansion of ketimine 4a. The results using linear alkyl-substituted vinylboronic acids as nucleophiles reaction with 4a indicate that the asymmetric alkenylation/ring-expansion can also be controlled by steric hindrance
