Chemical Properties
rose carboxylate is a mixture of isomers, bp0.8 kPa 102 °C, n20
D 1.4626, a
colorless to pale yellow liquid with rosy, spicy, fruity, and woody odor. For
its preparation, 3,6-dimethyl-6-hepten-2-one and 7-methyl-6-octen-3-one are
treated with ethyl diethylphosphoryl acetate to give a mixture of octadienoic
acid esters. Cyclization with sulfuric/formic acid yields the title compounds as a
mixture with additional isomers. Owing to its complex odor, it is used in
fine fragrances for shading.
