Chemical Properties

Methyl 3,6-Dimethylresorcylate is an odor-determining constituent of oakmoss absolute extract and forms colorless crystals (mp 145°C) with a mossy–earthy odor.

Preparation

Methyl 3,6-dimethylresorcylate is prepared by aromatization of corresponding hydroxycyclohexenones, for example, by dehydrogenation with a suitable Nhaloimide.
The intermediate hydroxycyclohexenone can be obtained either by reaction of dimethylmalonate with 4-hexen-3-one and 5-chloro-3-hexanone or by reaction of methyl propionylacetate with alkyl crotonate.
En annen vei starter fra det tilsvarende dimetyl-1,3-dihydroksybenzen, som er karboksylert, og den resulterende dihydroksymetylbenzoesyre er forestret.
