Chemistry & Uses
Uses in perfumery :
Lilial® is used in all types of perfumes to give heart to a jasmine, freesia, cyclamen, lotus, lily of the valley or lilac accord.
Year of discovery :
Discovered in 1956. Patent N°2,875,131 published in June, 11 1956 by Carpenter.M, Nutley, Easter W.Jr, Hasbrouck Heights for Givaudan Corporation
Natural availability :
Lilial® is not available in its natural state.
Isomerism :
Lilial® has an asymmetric carbon, giving rise to two possible enantiomers. These two isomers have a similar smell close to lily of the valley.
Synthesis precursor :
Lilial® forms a Schiff base with amines such as Methyl Anthranilate or Indole.
Synthesis route :
Lilial® is prepared in the same way as Cyclamen Aldehyde : a condensation of tert-butylbenzaldehyde (unlike isopropylbenzaldehyde) with propanal, followed by a catalytic hydrogenation of the compound obtained, allows to obtain Lilial®. Another synthetic route exists and consists in a catalytic hydrogenation of alpha-MethylCinnamaldehyde to obtain alpha-methyldihydroCinnamyl Alcohol. Following this first step, an alkylation using tert-butyl chloride or isobutene is operated to obtain a third reaction intermediate, then dehydrogenated to obtain Lilial®.
Stability :
Very unstable in various functional bases.
Aldehydes may form diethylacetals in alcoholic perfumes, with no real impact on their smell.
Most of the time, the occurrence of a benzenic cycle in a molecule causes a coloration of this molecule through time.
Other comments :
Very close to Lyral®. Lilial® is more stable than Cyclamen Aldehyde, for a similar synthetic route.
Lilial® is one of the 26 allergens in perfumery.
