Chemistry & Uses
Uses in perfumery :
Trans-2-cis-6-Nonadienol is used to make artificial violet leaf notes and in woody perfumes. It can also be useful to bring a strong mimosa top note. This molecule is used in very low quantity as it is very powerful, and it is diluted before usage.
Year of discovery :
Data not available.
Natural availability :
Trans-2-cis-6-Nonadienol is found on a natural state in Violet Leaf Absolute, and is partly responsible for its green and fatty smell. It can thus be extracted from it.
Isomerism :
The different diastereoisomers of Trans-2-cis-6-Nonadienol can be used in perfumery as they also have a green smell reminiscent of violet leaf and cucumber. They remain much less used than the first compound.
Synthesis precursor :
Trans-2-cis-6-Nonadienol can be used to synthesize its corresponding esters. For example, Trans-2-cis-6-Nonadienyl acetate has a green, fatty and nutty smell.
Synthesis route :
Trans-2-cis-6-Nonadienol is synthesized starting from cis-3-Hexenol, converted into cis-3-hexenyl chloride first, and then blending this product with pure magnesium to form a Grignard reagent. This reagent will undergo a reaction with acrolein, to form nonadien-3-ol, then converted into trans-2-cis-6-nonadienol thanks to an allylic rearrangement.
Stability :
Very unstable in acid cleaners and very alkaline products. Exclusively stable in shampoo, soap and fabric care bases.
Other comments :
In comparision to Trans-2-cis-6-Nonadienal, both molecules have a common violet leaf usage, but Trans-2-cis-6-Nonadienol still has a more floral and soft touch.
Both raw materials are also very costly.
