3.7- Dimethyl-2,6-octadien

These trivial names may be retained citral (3,7-dimethyl-2,6-octadienal), vanillin (4-hydroxy-3-methoxybenzaldehyde), and piperonal (3,4-methylenedioxybenzaldehyde). 

From West Indian lime oil, a trace low Foiling constituent, 1-methyl-1,3-(or 1,5 /74< 5 -3 7- -cyclohexadiene has been characterized (27). This compound, which possesses an intense and characteristic lime aroma, was later confirmed to be the 1,3-isomer [1489-56-1] (11). This compound can easily be made in a biomimetic way through the reaction of citral [5392-40-5] (3,7-dimethyl-2,6-octadienal) with citric acid (28,29). 

Nanostructured Pt(0) catalysts supported on cross-linked macromolecular matrices (Figure 5) have recently been evaluated in the hydrogenation of the a,P-unsaturated aldehyde, ( , Z)-3,7-dimethyl-2,6-octadienal (citral) (Scheme 10) [25]. 

The title compound, 88, the main metabolite of 13-cis-retinoic acid in mammals, has been synthesized27 as before via condensation of acetone-1,2,3-13C3 with 3,7-dimethyl-2,6-octadienal (citral), 89 (equation 33).
