ethyl 2,6,6-trimethylcyclohexa-1,3-ene-1-carboxylate Usage And Synthesis

Chemical Properties

The commercial quality also contains the α- and γ-isomers, ethyl 2,6,6-trimethyl- 2,4-cyclohexadiene-1-carboxylate and ethyl 6,6-dimethyl-2- methylene-3-cyclohexene-1-carboxylate. Ethyl 2,6,6-Trimethyl-1,3-cyclohexadiene-1-carboxylate is a colorless to slightly yellow liquid with a natural rose odor with aspects of apple cider and woody cedar. It is recommended for use in floral and fruity fragrances for shampoos, toiletries, and detergents.
The preparation of the material starts from mesityl oxide and ethyl acetoacetate, which are cyclized under acidic conditions.The resulting ethyl 4-oxo-2,6,6- trimethyl-2-cyclohexenecarboxylate is subsequently reduced and dehydrated.
