Usage

Chemical Properties

Ebanol is a mixture of isomers. It is a pale yellow liquid with a powerful woody, sandalwood odor withmusk aspect.Thematerial is obtained by aldol condensation of α-campholenaldehyde with 2-butanone. Subsequent isomerization of the double bond with potassium tert-butylate leads to a ??,??-unsaturated ketone, which is reduced with NaBH4 to yield a mixture of chiefly four diastereomeric alcohols. Alternatively, the ??,??-unsaturated ketone can be prepared by dehydration of the ketol, which is obtained when the aldol reaction is performed under special reaction conditions. It is used in fine fragrances as well as in functional products.

Preparation of 3-methyl-5-(2,2,3-trimethyl-3-cyclopenten-1-yl)pent-4-en-2-ol

The invention provides a preparation method of 3-methyl-5-(2,2,3-trimethyl-3-cyclopenten-1-yl)-pent-4-en-2-ol. The preparation method comprises the following steps: firstly, converting a compound of astructure of a formula (III) shown in the description into a compound of a structure of a formula (IV) shown in the description, and further converting the compound of the structure of the formula (IV) into a compound of a structure of a formula (I) shown in the description. According to the preparation, the compound of the structure of the formula (III) is subjected to isomerization and methylation in a same reaction system to obtain the compound of the structure of the formula (IV), so that the obtained product is high in purity and high in yield, in addition, steps of reactions are simplified, and industrial production can be achieved.

(2R*,3S*)-(E)-3-methyl-5-(2,2,3-trimethylcyclopent-3-en-1-yl)pent-4-en-2-ol

(2R*,3S*)-(E)-3-Methyl-5-(2,2,3-trimethylcyclopent-3-en-1-yl)pent-4-en-2-ol possesses a very intense creamy, woody, musk, sandalwood odor and is a valuable ingredient for use in fragrance compositions for its musk and sandalwood-like qualities. This odorant is more intense than any of the campholenic aldehyde derivatives that have been previously reported.
