1-OCTEN-3-OL Usage And Synthesis

Occurrence

Originally reported to be found in the mushroom Armillaria matsutake, a parasite growing on the radical hairs of Pinus densiflora in the forests of Japan. It has been isolated also from the essential oils of Mentha pulegium L., lavender and M. timjia.

Preparation

By a vinyl Grignard reaction on hexaldehyde or from amyl magnesium bromide and acrolein.

Metabolism

In the animal body secondary alcohols can undergo either conjugation with glucuronic acid or oxidation to a ketone, which may be excreted in the urine or expired air or further oxidized or reduced back to the alcohol. Studies of secondary alcohols containing more than seven carbon atoms have been limited to octan-2-ol. The conjugation of this alcohol in rabbits is low and much of the alcohol may be excreted unchanged . A dilute solution of synthetic (dl)-locten-3-ol fed directly into the rumen of a cow produced after 2-4 hr a maximum concentration in the milk of 20 μg octenol/litre. This concentration did not give the milk an off-flavour, and was not reported to have any other effects.
