Perkin-Oglialoro reaction was carried out on (3, 4-dimethoxyphenyl) acetic acid, o-nitrobenzaldehyde, (3, 4-methylenedioxyphenyl) acetic acid, and 2-nitro-4, 5-methylenedioxybenzaldehyde, and α-(3, 4-dimethoxyphenyl)-2-nitrocinnamic acid (I and II) and α-(3, 4-methylenedioxyphenyl)-2-nitro-4, 5-methylenedioxycinnamic acid (V and VI) were obtained. Effect of reaction conditions of this condensation on the formation ratio of the cis and trans isomers was examined.
