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 new series of 2,4-hexadienoic acid derivatives (S1-S42) has been synthesized and evaluated as antimicrobial agents against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Candida albicans, and Aspergillus niger. Quantitative structure-activity relationship (QSAR) investigation using Hansch analysis was applied to find out correlation between antimicrobial activities with physicochemical properties of the synthesized compounds. Various physicochemical descriptors and experimentally determined minimum inhibitory concentration values for different microorganisms were used as independent and dependent variables, respectively. The QSAR revealed that topological parameters especially molecular connectivity indices (χ2, 0χv, 2χv) were found to have overall significant correlation with antimicrobial activity of 2,4-hexadienoic acid derivatives. The statistical results of training set, cross-validated r2 and conventional r values gave reliability to the prediction of molecules with activity using QSAR models.

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).
