(R)-(-)-Tuberolactone
- Fruity, coconut, tonka note with metallic and
slightly fatty aspects. Base note, which is
essentially tuberose lactonic, has less volume
than (S)-(+)-enantiomer. In comparison to the
racemate this enantiomer is more pleasant with
regard to the tuberose note, but has less
volume.

(6R)-6-[(2Z)-pent-2-enyl]-5,6-dihydro-2H-pyran-2-one
