Chemische Eigenschaften
Colorless crystals; cedarwood odor. soluble in 11 parts of 95% alcohol. Combustible.
Occurrence
Found in the wood of several conifers, particularly cypresses and cedars, including Cedrus atlantica, Cupressus sempervirens, Juniperus virginiana (Fenarolfs Handbook of Flavor Ingredients, 1971).
Verwenden
(+)-Cedrol can be used as a starting material for the preparation of cedryl acetate by acetylation using acetic anhydride in the presence of an acid catalyst. It can also be incorporated as a precursor for the total synthesis of rare illicium sesquiterpene (+)-pseudoanisatin via selective C-H bond functionalization.
synthetische
From cedarwood by fractional distillation followed by recrystallization from suitable solvents of appropriate solid fractions.
Definition
A tertiary terpene alcohol.
Allgemeine Beschreibung
(+)-Cedrol is a crystalline hydrated product of α-cedrene, which is a sesquiterpene found in cedar-wood oil. It can be used as a fragrance ingredient in cosmetics, shampoos, and soaps as well as in non-cosmetic products such as cleaners and detergents. (±) Cedrol can be synthesized by intramolecular Diels-Alder reaction of alkyl cyclopentadiene.
l?uterung methode
Purify cedrol by recrystallisation from aqueous MeOH. It is estimated colorimetrically with H3PO4 in EtOH followed by vanillin and HCl [Hayward & Seymour Anal Chem 20 572 1948]. The 3,5-dinitrobenzoyl derivative has m 92-93o. [Stork & Clarke J Am Chem Soc 83 3114 1961, Beilstein 6 III 424.]
