A series of stereoisomeric o-methoxy-substituted 2,3-diphenyl propenoic acids and their methyl esters have been synthesized. The E isomers were prepared by a modified Perkin condensation (substituted benzaldehyde, phenylacetic acid, Et3N/acetic anhydride). The difficult to access Z isomers were obtained conveniently in good yields when the appropriate coumarin derivatives were allowed to react with KOH and CH3I in DMSO.

E(4') and Z(4)-α-phenylcinnamic acids were synthesized.These were been converted into isoaurones.The stereochemistry of these were determined by 1H NMR and Lanthanide induced shift (LIS) studies.
