Chemistry & Uses
Uses in perfumery :
Gamma-Octalactone is used in peach and coconut reconstitutions for its milky note, and in heavy floral accords as tuberose and jasmine.
Year of discovery :
Data not available.
Natural availability :
Gamma-Octalactone is found in the odoriferous principle of some processed and unprocessed food (apricot, peach, pineapple, blue cheese…), but does not exist on a natural state.
Isomerism :
Gamma-Octalactone has an asymmetric carbon, giving birth to two possible enantiomers. Nevertheless, a blend of these enantiomers is used in perfumery. Delta-Octalactone is a constitutional isomer of this molecule, but has a more woody and less milky note.
Synthesis precursor :
Gamma-Octalactone is not used for the synthesis of another molecule of olfactive interest.
Synthesis route :
Gamma-Octalactone is a cyclic lactone, synthesized as every other lactones. A reaction between acrylic acid and pentanol, in the presence of an alkaline sulfate or phosphate, ables to synthesize this molecule. An intramolecular esterification of 4-hydroxyoctanoic acid, catalized by a strong acid as sulfuric acid, also ables to obtain this compound. Eventually, biochemical synthesis routes are being studied.
Stability :
Lactones tend to polymerize through time, making them more viscous and leading to a phase shift in alcohol.
