Asymmetric Nickel-Catalyzed Negishi Cross-Couplings of Secondary α-Bromo Amides with Organozinc Reagents

A Ni/Pybox catalyst achieves the asymmetric cross-coupling of secondary alpha-bromo amides with organozinc reagents. The process tolerates a variety of functional groups and affords the desired product in good yield and in high enantiomeric excess.
