Asymmetric nickel-catalyzed Negishi cross-couplings of secondary alpha-bromo amides with organozinc reagents

J Am Chem Soc. 2005 Apr 6;127(13):4594-5. doi: 10.1021/ja0506509.

Abstract

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.
