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-naphtalenecarba ldehyde, which aldehydes are not only useful as starting products for the preparation of the corresponding nitriles, but also as perfuming ingredients.
我们披露了一种新的腈,即5,6,7,8-四氢-3,5,5,6,7,8,8-庚基-2-
萘基腈,这是一种具有
麝香和泥土气味的
香料成分,而且在特别具有侵蚀性的介质中(例如止汗剂基质)非常稳定。该化合物可以呈现为外消旋体或其一种手性异构体的形式。该异构体可以从醛中获得,即(-)-(6S,7S)和(+)-(6R,7R)-5,6,7,8-四氢-3,5,5,6,7,8,8-庚基-2-
萘基
甲醛,这些醛不仅可用作制备相应腈的起始原料,而且也可用作
香料成分。
