✦ Synopsis

of the pyranols 3 and 4 generated (6S)-and (6R)tetrahydro-2,2,6-trimethyl-6-vinyl-2H-pyran-3-ones 9 and 10 respectively. Coinjection by chiral GC showed (6S)-tetrahydro-2,2,6-trimethyl-6-vinyl-2Hpyran-3-one 9 to be identical to the component produced by Sissinghurst Pink and Pink Parfait. In olfactometer studies, WFT were attracted to 5 but not to 3 or to a mixture of 5 and 3 in the ratio produced by Sissinghurst Pink cultivar, suggesting that there may be separate olfactory receptors for the two diastereoisomers of linalool oxide and that other components of the ¯ower volatiles must contribute to the attractiveness of the odours from Tapien Pink and Pink Parfait.
