In the synthesis of pinastric acid by Volhard's method the alcoholysis of 4-methoxypulvinic dilactone yields pinastric acid and an equal amount of an isomeric compound having the same chemical properties as pinastric acid and giving the same degradation products, but differing in physical properties and in the properties of the derivatives. The new compound is therefore a stereoisomer and is named isopinastric acid. It seems to be the trans-trans form with reference to the 1:4-diphenylbutadiene system, pinastric acid being cis-trans. This interpretation is supported by the study of absorption spectra.
