Synthetic and spectroscopic studies of structural analogs of piper amides - The 5-aryl-2E,4E-pentadienamides

The methyl esters and piperidides of fourteen 5-aryl-2E,4E-pentadienoic acids have been synthesized starting from the corresponding aryl aldehydes.

Substituent Effects on Carbon-13 NMR Chemical Shifts of Side-chain Carbons in 5-Aryl-2E,4E-pentadienoic Acid Derivatives

The 13C NMR spectra of two series of 5-aryl-2E,4E-pentadienoic acid derivatives, viz. the methyl esters and piperidides have been determined.The chemical shifts of C-2 and C-4 show very good correlations with the Hammett ?+-constants for all the substituents investigated, except for the para-nitro group which is capable of excerting a strong -R effect.A possible explanation for this has been advanced.Hammett correlations between substituents and the chemical shifts of both C-3 and C-5 carbons using ?0 parameters are less satisfactory.A reverse chemical shift effect has been observed for these two centres.
