Tetralinic nitriles, their use as perfuming ingredients and aldehyde intermediates for their preparation

摘要

We disclose a novel nitrile, i.e. 5,6,7,8-tetrahydro-3,5,5,6,7,8,8-heptamethyl-2-naphthalenecarbonitrile, a perfuming ingredient having a musky, earthy odor, and which is remarkably stable in particularly aggressive media such as for instance antiperspirant bases. This compound may present itself as a racemate or in the form of one of its optically active isomers. Said isomers can be obtained from aldehydes, namely (-)-(6S,7S) and (+)-(6R,7R)-5,6,7,8-tetrahydro-3,5,5,6,7,8,8-heptamethyl-2-naphtalenecarbaldehyde, which aldehydes are not only useful as starting products for the preparation of the corresponding nitriles, but also as perfuming ingredients.
