The Prins reaction on isolongifolene has also produced a number of useful products (185,186). All the products have amber, woody odors, and are known under the names of Amborol, Amboryl Formate, and Amboryl Acetate. 

Wood Oil). Guaiyl acetate is a yellow to amber liquid with a weak but lasting, woody odor. It is used in perfumery for tea-rose and wood nuances. 

Vetiveryl acetate is a light yellow liquid with a dry, fresh-woody odor. It is a popular fragrance mixture that is frequently used in luxury perfumery it is also used as a fixative in many fine fragrances. 

C13H22O2, Mr 210.32 is a mixture of isomers, bpo kPa 102 °C, ng 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 isomers [134]. With its complex odor picture it is used in fine fragrances for shading. 

Clove stem oil is obtained in ca. 5% yield by steam distillation of the dried flower stems. It is a yellow to light brown oil with a sweet-spicy, slightly woody odor similar to that of bud oil but without the fresh-fruity top note. 

The concretes are green to brown waxy pastes the absolutes are more or less viscous liquids with an earthy, mossy, woody odor and a slight phenolic, leather note. 

Cananga oil is produced by steam distillation of the flowers of Cananga odorata (DC) Hook. f. et Thoms, subsp. macrophylla. The yield, based on the weight of the flowers, is ca. 1% The oil is a light to dark yellow liquid with a characteristic, floral, slightly woody odor. 

Oxidation of pentynediol 119 by Mn02 followed by interaction with p-TSA led to acetylenic derivative 120 that possesses extremely strong and diffusive violet and freesia, raspberry, woody, odors similar to )S-ionone. But the odor of allene derivative 122, also prepared from diol 119 by dehydration with LiAIH4 and further oxidation with Mn02, was rather unpleasant (85LA950). 

Ci3H2o02 Mr 208.30, bph5 122 °C, df 0.9811, rag0 1.4733, [a]D -30.9°, is not found in nature and has a fresh-fruity-woody odor. It is prepared by acetylation of (-)-nopol with acetic anhydride. (-)-Nopol is obtained from (- )-/ -pinene and paraformaldehyde in a Prins reaction. 

C17H28O2, Mr 264.41, bpo2 kPa 118-123 °C, dg 0.965-0.990, ng 1.489-1.495, is obtained by esterification of guaiac wood oil with acetic anhydride and consists of the acetates of the natural sesquiterpene alcohols guaiol and bulnesol (see Guaiac Wood Oil). Guaiyl acetate is a yellow to amber liquid with a weak, but lasting, woody odor. It is used in perfumery for tea-rose and wood nuances. 

C15H30O, Mr 226.40, %).0i33kPa 150 °C, df 0.896-0.902, ng 1.470-1.476, is a colorless liquid with a highly diffusive, powdery-woody odor. It is a mixture of the cis and trans isomers. The trans isomer has a more distinct animal and ambery character [112],... 

C15H30O2, Mr 242.40, is not known in nature. It is a colorless liquid, bpo.i pa 94 °C, df5 0.931, ng° 1.463-1.467, with a noble woody odor with ambergris nuances. It is prepared by reaction of cyclododecanol with paraformaldehyde/hydrochloric gas to give cyclododecyl chloromethyl ether, which is treated with sodium ethylate [116]. 

Ci2Hi602, Mr 192.26, 6plkPa 119-121 °C, df 1.0714, ng 1.4935, is a colorless liquid with a herbal, fresh-woody odor. It consists of a mixture of isomers that is obtained by addition of acetic acid to dicyclopentadiene in the presence of an acid catalyst. It is used for perfuming soaps, detergents, and air fresheners.
