Other names :
Burgenal ; 3-(4-tert-butylphenyl)propanal ; 4-(1,1-dimethylethyl)-benzenepropanal ; Para-tertbutyl dihydrocinnamaldehyde ; Para-tertbutyl dihydrocinnamic aldehyde ; 3-(4-tert-butylphenyl)propionaldehyde ; 4-(1,1-dimethyl ethyl) benzene propanal ; Langeonal ; Lilional ; Liliphenal ; 3-[4-(2-methyl-2-propanyl)phenyl]propanal
Volatility :
Heart
Uses in perfumery :
Bourgeonal is used in all types of perfumery, in floral-aldehydic, green notes. Often used for its stability in soap and detergent bases, in addition to alcoholic perfumery.
Natural availability :
Bourgeonal is not available in its natural state.
Year of discovery :
1959
Other comments :
Compared to Lilial® or Silvial®, Bourgeonal is a floral-aldehydic molecule also having a green note, making the difference with other molecules of this type.
Price Range :
€€
Stability :
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
Exclusively stable in fabric conditioners, shampoos and hair conditioners.

Synthesis route :
Bourgeonal can be synthesized from 4-tert-Butyl benzaldehyde by an aldol reaction with Acetaldehyde. The intermediate product that is obtained is 4-tert-Butyl Cinnamaldehyde. A catalytic hydrogenation converts this intermediate into Bourgeonal. Another synthetic route reacts 4-tert-Butyl benzene with acrolein diacetate in the presence of a Lewis acid.
Then, the intermediate product is subjected to a saponification.
Synthesis precursor :
Bourgeonal forms a Schiff base by reaction with Methyl Anthranilate or Indole for example.
Isomerism :
The meta and ortho isomers of Bourgeonal are not used in perfumery.
Cyclamen Aldehyde is a positional isomer of Bourgeonal. However, its smell is quite different, as it is more marine. Both have an aldehydic and floral-white flowers smell.
