Oil of jasmine

Benzyl Acetate.—This ester is a constituent of the oils of jasmin, ylang-ylang, and similar flower oils. It has not a very intense odour, but is essential to the successful production of such perfumes as artificial jasmin. It has the formula CgHg, CH2. O. OCCH3. It is a colourless oU, boiling at 206° at ordinary pressure, and has a specific gravity 1-0570 at 16° and a refractive index 1-5034 . The propionic ester has the formula C0H5CH2OOCCH2CH3, and closely resembles the acetate in odour. 

Jasmone, CjjHjgO, is a ketone found in essential oil of jasmin, and also in neroli oil. It is a dark-coloured liquid with a powerful jasmin odour, and having the following characters —... 

Para-cresol, which is also a constituent of coal-tar creasote, occurs in the es ential oils of jasmin and cassie flowers. It is a crystalline sub-... 

Indol, CgH N, is the mother substance of the indigo group of compounds. It exists in various essential oils including neroli oil and oil of jasmin flowers. It is a crystalline compound, melting at 52° and boiling at 253° to 254°. Its odour is powerful and disagreeable, being distinctly faecal in character. Its constitution is as follows —... 

Many esters have fragrant odors and contribute to the flavors of fruits. For example, benzyl acetate, CH3COOCH2C6Hs, is an active component of oil of jasmine. Other naturally occurring esters include fats and oils. For example, the animal fat tristearin (12), which is a component of beef fat, is an ester formed from glycerol and stearic acid. 

Methyl anthranilate occurs in oil of orange blossoms (neroli oil), oil of orange peel, and in the essential oil of jasmine flowers, and is extensively used in perfumery. 

Benzyl Alcohol, NF. Ben/yl alcohol (phenylcarbinol. phenylmethanol) occurs naturally as the unesteriried form in oil of jasmine and in esters of acetic, cinnamic, and benzoic acids in gum benzoin,. storax re.sin. Peru balsam, tolu balsam, and some volatile oils. It is. soluble in water and alcohol and is a clear liquid with an aromatic odor. 

Esters are colorless, volatile liquids that often have pleasant odors. Many occur naturally in flowers and fruits. Isoamyl acetate (Fig. 7.27a) is generated in apples as they ripen and contributes to the flavor and odor of the fruit. Benzyl acetate, the ester formed from acetic acid and benzyl alcohol (see Fig. 7.27b), is a major component of oil of jasmine and is used in the preparation of perfumes. 

Jasmonic acid was first discovered as its methylester (2) an odoriferous compound from the essential oil of jasmine (Jasminum grandiflomm L.) [3], Early interest in this compound centered on its fragrant properties but recently, jasmonic acid and its methyl ester have fascinated plant physiologists and molecular biologists because they have been shown to possess hormonal activity [4], can act as a senescence-promoting substance [5], and can induce JIP (jasmonate induced proteins) [6] and soybean vegetative storage proteins [7],... 

Benzyl acetate is a pleasant-smelling esterfound in the essential oil of jasmine flowers and is used in many perfume formulations. Starting with benzene and using any other reagents of your choice, design an efficient synthesis for benzyl acetate. 

Ethyl butyrate is responsible for the sweet aroma of pineapples. Other common esters include methyl butyrate, found in apples, and ethyl formate, an artificial rum flavor. Several perfumes use esters to impart a pleasant smell. For example, oil of jasmine contains benzyl acetate, a molecule found in the jasmine flower. 

Ethyl butyrate is found in pineapples. Methyl butyrate is found in apples. Ethyl formate is found in artificial rum flavor. Benzyl acetate is a component of oil of jasmine. 

Cyclopentenone Polyolefinic Compounds Jasmone.—Several new routes to c/j-jasmone (175), an important constituent of the essential oil of jasmine, have been described. Ellison and Woessner have outlined a convenient route to the 1,4-diketone (174), which readily... 

An important ketone obtained from the essential oil of jasmine flowers Jasminum grandiflorum, Oleaceae) is (Z)-3-methyl-2-(pent-2-en-l-yl)-2-cyclopenten-l-one, also called cis-jasmone (8-48), which belongs to the group of structurally related compounds called jasmonoids (see Section 3.8.1.8.5) that are used in perfumery and cosmetics. Jasmine flowers are used to scent tea in China. 

Artificial oil of jasmin compounded on the lines of the above-mentioned facts is now a regular article of commerce. It closely resembles the natural perfume, except that it is less delicate, and is-well adapted for high-class toilet perfumery.
