A series of p-substituted (E)- and (Z)-α,β-dimethylcinnamic acids has been prepared and pharmacologically tested.The configurations of the acids prepared were determined from their NMR spectra.The UV spectra and the acid dissociation constants are reported.The collected data show that an extensive conjugation between the aryl and carboxy groups via the double bond does not exist, due to the steric hindrance of the α,β-dimethyl substitution on the cinnamic system.
