A practically feasible, diastereoselective conjugate addition-elimination
reaction of a chiral nickel(II) complex of glycine 1 with
allylic acetates 2 is described. The reaction
pathway was successfully controlled, and the desired formation of
a carbon-carbon bond was exclusively obtained with high
diastereoselectivity. This reaction is an attractive route for the
asymmetric synthesis of previously unavailable chainlike glutamic
acid derivatives.
