Only one out of the four possible trans isomers of the important perfumery alcohol Norlimbanol® (1) possesses a very strong amber-woody smell, the isomer 1A with (1′R,3S,6′S) absolute configuration. Its enantiomer 1B is almost odorless and devoid of amber-woody character, whereas the diastereoisomers 1C and 1D are considerably weaker and perceptible only by the most-sensitive persons. The same is true
Norlimbanol in general and particularly its isomer mixture Timberol®, an amber-woody fragrance, is able to specifically inhibit the trimethylamine-induced h TAAR5 activation up to 96%. Moreover, human psychophysical data showed that the presence of Timberol® increases the olfactory detection threshold for the characteristic fishy odor of trimethylamine by almost one order of magnitude.
