(+)-(S)-1-tert-butyl-2,3,3a,4,6,7-hexahydro-3a-methylinden-5-one - Odor description (10% DPG, blotter): dark woody (woody facet of Cashmeran), agrestic odor with slightly smoky aspects, and nuances of vetiver and oud, and with slightly floral facets (rosy in Mefrosol direction). The odor is more floral and woody than that of the (R)-enantiomer. Odor Threshold (GC) = 10.6 ng L–1 air = (+)-(7aS)-3-tert-Butyl-7a-methyl-4,5,7,7a-tetrahydro-1H-inden-6(2H)-one Ref: Felker, I., Pupo, G., Kraft, P., & List, B. (2015).

(-)-(R)-1-tert-butyl-2,3,3a,4,6,7-hexahydro-3a-methylinden-5-one - Odor description (10% DPG, blotter): dark woody, agrestic odor with fruity aspects in Cashmeran direction and nuances of raspberry and orris, and slightly rooty, oud and vetiver facets, somewhat recalling epoxy cedrene. The odor is sweeter and fattier than that of the antipode. Odor Threshold (GC) = 5.95 ng L–1 air = (-)-(7aR)-3-tert-Butyl-7a-methyl-4,5,7,7a-tetrahydro-1H-inden-6(2H)-one Ref: Felker, I., Pupo, G., Kraft, P., & List, B. (2015).
