(1S,5R)-(+)-Myrtenal - Probability levels of significant differentiation between the enantiomer pairs - >99.0% with 96 untrained panelists; >99.0% with 28 expert panelists; overall >99.9% (all 124 panelists). Theimer's personal comments indicates that he had no problem in differentiating the enantiomers - the d- and l-myrtenals suggested cuminic aldehyde and cyclohexyl acetaldehyde respectively. = (1S,5R)-6,6-dimethylbicyclo[3.1.1]hept-2-ene-2-carbaldehyde Ref: E.T. Theimer and Mina R. McDaniel, Odor and optical activity, J. Soc. Cosmet. Chem. 22, 5-26 (1971) Commercial Myrtenal has been described by Mosciano, et. al. - "cooling, green, minty with spicy woody notes" odor and a "minty, green and cooling with powdery spicy notes" taste at 30 ppm. (Perfumer & Flavorist, Vol. 15, January/February 1990, p. 24)
