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
