3- Octyl Acetate

When bicyclo[2.2.2]octyl brosylate was solvolyzed in acetic acid containing sodium acetate, the products were a mixture of bicyclo[2.2.2]octyl acetate and bicyclo[3.2.1]octyl acetate, each of which was optically active. The formation of bicyclo[2.2.2]octyl acetate was found to proceed with 82 15% retention of configuration, a result which is in...

The reaction of 1-chlorooctane with CH3CO2- to give octyl acetate is greatly accelerated by adding a small quantity of iodide ion. Explain.

A perceptible marker of the olibanum fragrances coming from Somalia, Sudan, or Ethiopia is the aliphatic octyl acetate marked by a distinct acrid smell. Boswellia carterii contains up to 50% of the aliphatic octyl acetate, demonstrated by the strong stinging smell of the fume, whereas Boswellia serrata (its common name in India is salai guggul) contains none or only small amounts of it and, consequentiy, does not have such a harsh smell.

The samples coming from Eritrea, Jerusalem and Liban could be undoubtedly attributed to B. papyrifera, because of their characteristic constituents octanol (18), octyl acetate (40), linear caboxylic acids (10, 20, 36, 49, 63), incensole (127) and its acetate and oxide derivatives (129-131). 

The GC-MS chromatogram, obtained after SPME of the traditional incense from a monastery of Mount Athos, is presented in Figure 10.7a. The occurrence of octanol (18), octyl acetate (40), incensole (127), incensole acetate (129), incensole oxide (130) and incensole oxide acetate (131), allowed the identification of a B. papyrifera olibanum (Figure 10.7b) in a mixture with other substances, most probably Damask rose and jasmine. 

Tab. 5.2 Synthesis ofn-octyl acetate under MW + PTC conditions (Synthewave, 5 min, 160°C).

The name of this ester is n-octyl acetate, which is the odor of oranges. Esters are formed from the reaction of a carboxylic acid with an alcohol. 

Here are some additional examples of esters as aromas or flavors propyl acetate is the aroma of pears pentyl acetate is the aroma of bananas octyl acetate is that for oranges. 

Esters, which contain the C 0 C functional group, have many uses in medicine, industry, and living systems. In medicine, a number of important pharmaceutical agents, including aspirin and the local anesthetic benzocaine, are esters. In industry, polyesters such as Dacron and Mylar are used to make synthetic fibers and films. In nature, many simple esters are responsible for the fragrant odors of fruits and flowers. For example, pentyl acetate is found in bananas, and octyl acetate is found in oranges. 

Comparison of the taste threshold with estimated concentration in orange juice (where available) in Table I reveals that in all cases except octyl acetate and a-pinene, the concentration in orange juice exceeds the taste threshold in water for most values reported. Patton and Josephson (17) postulated that components present in a food at above threshold level make a positive contribution to the flavor, while those present at below threshold level make little or no contribution to flavor. This generalization is now considered an oversimplification, for synergistic effects among food constituents have been shown to decrease the threshold level of some compounds, and nonvolatile constituents are known to either increase or decrease the taste threshold of certain volatile and nonvolatile constituents.
