Total syntheses of spirovetivanes and khusimone

The majority of these substances belong to the sesquiterpene group of natural products. Among these α-vetivone, β-vetivone, the norsesquiterpene khusimone, and three biogenetically derived C12-ketones provided the most exciting chemistry. Since the spiroketone and khusimone appear to play a significant role in the reconstitution of the essential oil, we have developed total syntheses of these substances. In an earlier synthesis of the spiroketone, β-vetivone was utilized as starting material; and more recently it has also been prepared by a photochemical route. Among the many published syntheses of β-vetivone two deserve special mention because of their elegance and stereo selectivity.

Effects of Structural Modifications on the Odour of Jasmone Analogues

The odour of 2-alkylcyclopentanones can be radically affected by substituents on the first or second carbon atoms of the side chain, substituents further along the chain having a much lesser effect on the odour character. It is postulated that these effects could be rationalised in terms of obstruction of the carbonyl group by a substituent on the first carbon of the side chain or disruption of the side chain conformation by one on the second position
