Sunghee Son et al.
Journal of the American Chemical Society, 130(9), 2756-2757 (2008-02-09)
Complementing previous advances in allylation chemistry, an effective nickel/Pybox catalyst for regioselective asymmetric Negishi cross-couplings of racemic secondary allylic chlorides with readily available organozinc halides has been developed. The method has been applied in two key steps of a formal
