Zur Konstitution des Limonins I. Über den Verlauf der alkalischen Hydrolyse von Limonin und Limonol

The ketonic bitter principle limonin and the corresponding secondary alcohol limonol have been shown to undergo a deep‐seated hydrolytic cleavage in the presence of alkali. The course of these cleavages which lead to a new series of compounds with 20 and 21 carbon atoms respectively, involves the splitting of a β‐substituted furan nucleus. These as well as previous findings are interpreted in terms of the partial formula.
