Trade Name. Kohinool (IFF). 4631, occurs, for example, in cucumber oil, violet leaf oil, and violet blossom oil. It is a colorless liquid with an intense, heavy-fatty, green odor, reminiscent of violet leaves. The starting material for the synthesis of 2-trans6-cis-nonadien-1-ol is cis-3-hexen-1-ol, which is converted via its halide into the corresponding Grignard reagent. The Grignard reagent is reacted with acrolein to give 1,6-nonadien-3-ol, which is converted into 2-trans-6-cis-nonadien-1-ol by allylic rearrangement.
Together with its esters, linalool is one of the most frequently used fragrance substances and is produced in large quantities. In the presence of acids, linalool isomerizes readily to geraniol, nerol, and -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.
Citronellol is still obtained mainly from geranium oil by saponi®cation followed by fractional distillation. Although of high odor quality, it does not possess the true (ÿ)-citronellol odor due to impurities. Much larger quantities of ()- and (Æ)-citronellol are used and are prepared by partial or total synthesis. 1. Synthesis of ()- and (Æ)-Citronellol from the Citronellal Fraction of Essential Oils. , Raney nickel). Similarly, (Æ)-citronellol is prepared from the (Æ)-citronellal fraction of Eucalyptus citriodora oil.
