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.

Synthesis of esters and amides of 2,4-(2 E, 4 E) hexadienoic acid are reported. The authors have tried to modulate the polarity of these compounds by introducing sequences with hydroxyl, amino groups, ether, thioether functions and halogen atoms or heterocycles. A gain in bacteriostatic activity, compared with sorbic acid has been stated in some cases, it is accompanied by either a breakdown (compounds 3, 38, 51, and 54) or a maintenance of fungistatic activity (compounds 5, 10 and 17).
