A method for catalytic asymmetric alkylation of conjugated dienyl amides has been developed and it allows efficient and high-yielding transformations of a wide range of polyconjugated amides into the corresponding chiral products. Smooth addition of organomagnesium reagents to relatively unreactive dienyl amides with excellent 1,6- and 1,4-selectivities, as well as enantioselectivites above 90 %, is achieved owing to the complementary action of the Lewis acid and a chiral copper-based catalyst.

A pentadienyl anion 7a generated from 2-N-methylanilinohepta-3,5-dienenitrile reacted at the γ-site with halogenoalkanes to give predominantly the products 9γ-22γ having the 2Z,5E-configuration, while it reacted at the ε-site with conjugated aldehydes to
