(-)-(9R,10S)-10-Acetyl-9,10-dimethylbicyclo[6.4.0]dodec-1(8)-ene - it emanates a strong woody-ambery odor reminiscent of Iso E Super, Georgywood and cedarwood, and has an odor threshold of 0.19 ng/L air which is about 100 times stronger than its enantiomer. Odor Threshold = 0.19 ng/L air = (-)-1-[(1R,2S)-1,2-dimethyl-1,2,3,4,5,6,7,8,9,10-decahydrobenzo[8]annulen-2-yl]ethanone Ref: Philip Kraft, Sofia Gallo, (-)-(9R,10S)-10-Acetyl-9,10-dimethylbicyclo[6.4.0]dodec-1(8)-ene: Optical Resolution, Catalyst Systems, Derivatives and Olfactory Properties, Synthesis 2004: 381-388.

(+)-(9R,10S)-10-Acetyl-9,10-dimethylbicyclo[6.4.0]dodec-1(8)-ene - possesses a similar odor character to the (-)-(9R,10S)-enantiomer but is about 100 times weaker. Odor Threshold = ca. 20 ng/L air = (+)-1-[(1S,2R)-1,2-dimethyl-1,2,3,4,5,6,7,8,9,10-decahydrobenzo[8]annulen-2-yl]ethanone Ref: Philip Kraft, Sofia Gallo, (-)-(9R,10S)-10-Acetyl-9,10-dimethylbicyclo[6.4.0]dodec-1(8)-ene: Optical Resolution, Catalyst Systems, Derivatives and Olfactory Properties, Synthesis 2004: 381-388.
