In comparison with the araliphatic alcohols discussed in Section 2.5.2, very few phenol alcohols are used as fragrance and flavor materials. Neither the alcohols corresponding to vanillin, ethylvanillin, and heliotropin nor their esters have special organoleptic properties. Anise alcohol and its acetate are the only products that are used to some extent in perfume and aroma compositions. 

Pure anise alcohol for perfumery and flavor purposes is prepared by hydrogenation of anisaldehyde. It is used in perfumery in blossom compositions (e.g., lilac and gardenia types) and in flavors for confectionery and beverages.

Manufacturing process Several methods exist for reduction of o-anisic aldehyde to o-anisic alcohol, however, direct reduction by hydrogen using Raney-Nickel catalyst system at 90-100° C and 5-7 atm pressure has been commercially most attractive. Most of the key players of p-anisic alcohol such as BASF, Givaudan, Koffoeks, etc. also produce some quantities of o-anisyl alcohol. Application areas include flavor and fragrance, pharmaceuticals, etc. Global demand has been estimated at 300-350 tpa. 

Para-anisic aldehyde and p-anisic alcohol are two important p-cresol derivatives which have provided critical feedstocks for some of the important bulk drugs. Trimethoprim made from 3,4,5-trimethoxybenzaldehyde is another example. p-Cresol has already replaced gallic acid as the preferred starting material for 3,4,5-trimethoxy benzaldehyde. As more R D work is undertaken, there will no doubt emerge more finished pharmaceutical items not only from p-cresol but also from o-cresol and m-cresol. Growth of meZo-cresol has indeed been remarkable after the process was commercialized for... 

Preparation from p-cresol via p-anisic aldehyde via p-anisic alcohol. 

Perfumery grades of pi-anisic aldehyde and 79-anisic alcohol made from p-cresol are used by most of the top aroma chemicals companies such as IFF, Givau-dan, BASF, H R, Dragaco, S.H. Kelkar, etc. 

Bis(4-methylphenyl)bismuth A -(4-methylphenyl)sulfonylamide 4 is obtained in moderate yield by the reaction of tris(4-methylphenyl)bismuth [A -(4-methylphenyl)sulfonyl]imide with anise alcohol or cinnamyl alcohol [96JCR(S)24]. This amide is insoluble in benzene, but soluble in chloroform, and not so sensitive to oxygen md moisture in the solid state. However, it slowly decomposes to tris(4-methylphenyl)bismuthine and a white powdery deposit when the amide is stood in CDCI3. 

CsHgC, Mr 136.15, pi.85kPa 132 °C, df 1.1192, n 1.5703, occurs in many essential oils, often together with anethole. It is a colorless to slightly yellowish liquid with a sweet, mimosa, hawthorn odor. p-Anisaldehyde can be hydrogenated to anise alcohol and readily oxidizes to anisic acid when exposed to air. Synthetic routes to anisaldehyde start from p-cresyl methyl ether, which is oxidized e.g. by manganese dioxide or by oxygen or peroxy compounds in the presence of transition metal catalysts [170], [171].
