Cyclamen

Famesol is manufactured from nerohdol by isomerization over a vanadium catalyst (55). Famesol occurs in several essential oils, such as ambrette seed, neroh, rose, cyclamen, and jasmine it is also used in floral and oriental fragrances. 

The process mentioned above was successfully applied to a short and efficient synthesis of two perfume compounds, cyclamen aldehyde and foliaver (Scheme 10).32...

Colorimetric analyses performed in the reflection mode have been used to determine colors of various flowers" as well as the colors and color development of fruits and berries. In an interesting study, the cyclamen red (or pink) colors of some carnation cultivars have been found to be based on the macrocyclic anthocyanin, pelargoni-din 3,5-diglucoside (6",6" -malyl diester).The CIELAB coordinates revealed that these flowers showed similar colors as some rose cultivars, which, however, were mainly based on a very different pigment, cyanidin 3,5-diglucoside.

Uses. Because of its fine, flowery odor, hydroxydihydrocitronellal is used in large quantities in many perfume compositions for creating linden blossom and lily of the valley notes. It is also used in other blossom fragrances such as honeysuckle, lily, and cyclamen. 

Uses. Cyclamenaldehyde is an important component for obtaining special blossom notes in perfume compositions, particularly the cyclamen type. Because of its fresh-flowery aspect, it is also used as the top note in many other blossom fragrances. 

C11H14O3, Mr 194.23, is not found in nature. It is a colorless slightly viscous liquid, df 1.154-1.162, Wp 1.529-1.534, with a tenacious honey, cyclamen, and rose note. It is prepared by acetalization of phenylacetaldehyde with glycerine. 

Farnesol 71 (Structure 4.18) is widely distributed in flower oils such as rose, acacia and cyclamen. 

A subcosmopolitan family of the northern hemisphere, the Pri-mulaceae are known for their garden flowers. Occasional alkaloids have been noted in Cyclamen and Primula.

The green side of the perfume which is less pronounced than in Fidji, and more floral, is based on phenylacetaldehyde and cA-3-hexenyl acetate with perhaps a trace of galbanum. Narcisse absolute may also be used. Other materials that add to the building up of the white flower character are Lilial and cyclamen aldehyde in addition to the hydroxycitronellal and Lyral. The tuberose character can be given by the use of the Schiff base derived from methyl anthranilate and Helional, or by the direct addition of methyl anthranilate. The mossy side of the perfume is represented by Evemyl. 

In the first type, which includes aldehyde C12 lauric and phenylacetaldehyde, the balance of the reaction lies in favor of the combined molecule. In the second, however, to which belong aldehyde C12 MNA, cyclamen aldehyde, hydratropic aldehyde, and Lilial, the balance lies more toward the original material. Most ketones also behave in this way. The third type, which includes amyl and hexyl cinnamic aldehydes, do not undergo the aldol reaction and are therefore more stable. Aldehydes such as anisaldehyde and Triplal, in which the —CHO is linked directly to a ring structure, are also less reactive. 

The nomenclature of the aromatic aldehydes is somewhat confusing because in the past a number of different conventions were used in the naming of organic compounds. While some, such as cyclamen aldehyde, and vanillin, are usually referred to by their common names, others are referred to either by a single chemical name or by a number of different chemical synonyms.
