Studies on the Structure of Itaconitin. V. On the Alkaline Hydrogenation Product of Anhydroitaconitin

Abstract

Methylanhydroitaconitin (III) which was prepared from anhydroitaconitin by treatment with the methylating agent followed by hydrolysis gave 2-methoxy-4-methylbenzaldehyde on ozonolysis. While the ozonolysis of the compound, C₁₄H₁₈O₅, which was obtained by alkaline hydrogenation of anhydroitaconitin yielded cisoid-dihydrohaematinic acid (XI). From these and other experimental results the structure of the compound, C₁₄H₁₈O₅ was established as XII.
