Linalool tetrahydrolinalool

C10H22O, Mr 158.28, bp s ki a 78-79°C, d ° 0.8294, ri 1.4335, is a constituent of honey aroma. It is a colorless liquid with a linalool-like odor that is slightly fresher but distinctly weaker than that of linalool. Tetrahydrolinalool is prepared by catalytic hydrogenation of linalool and is used as a substitute for the less stable linalool in perfuming aggressive media. 

In the presence of acids, linalool isomerizes readily to geraniol, nerol, and a-terpineol. It is oxidized to citral by chromic acid. Oxidation with peracetic acid yields linalool oxides, which occur in small amounts in essential oils and are also used in perfumery. Hydrogenation of linalool gives tetrahydrolinalool, a stable fragrance material. Its odor is not as strong as, but fresher than, that of linalool. Linalool can be converted into linalyl acetate by reaction with ketene or an excess of boiling acetic anhydride [34]. 

The acyclic terpene alcohols geraniol, linalool, and citronellol are the most important terpene alcohols used as fragrance and flavor substances. Geraniol and linalool are, in addition to nerol and lavandulol, primary products in terpene biosynthesis. The fully saturated alcohols tetrahydrogeraniol and tetrahydrolinalool are also...

Linalool (206) and tetrahydrollnalool (325) were converted by suspension cells of C. roseus to give 1-hydroxylinalool (219) from linalool (206) and 3,7-dimethyloctane-3,5-diol (326), 3,7-dimeth-yloctane-3,7-diol (327), and 3,7-dimethyloctane-3,8-diol (328) from tetrahydrolinalool (325) (Hamada and Furuya, 2000 Flamada et al., 2004) (Figure 19.24). 

Methyl-5-hepten-2-one, the main intermediate to linalool, can be further converted to important aroma chemicals such as geraniol, tetrahydrolinalool, methyl ionones, and others. 

Linalool can be hydrogenated to dihydroUnalool [18479-49-7] and tetrahydrolinalool [78-69-3] (97), both of which are used in perfumery. The use of the latter has increased because of its superior performance in harsh media, such as household cleaners containing hypochlorite bleach (which attacks the double bonds of linalool).
