Aldehyde C-11 MOA

Other comments :

In comparision with Aldehyde C-12 MNA, Aldehyde C-11 MOA has one additional carbon atom. This changes it into a more fruity, a deeper and more agrestic smell.

Stability :

Aldehydes may form diethylacetals in alcoholic perfumes, with no real impact on their smell

Uses in perfumery :

Used in coriander leaves notes (Coriander Leaf EO), in sparkling liquors notes, in eaux fraiches and zesty notes, bringing an agrestic undernote.

Year of discovery :

Data not available.

Isomerism :

Aldehyde C11 MOA is a constitutional isomer of Aldehyde C11 Undecylic. It only has one ramification, while Aldehyde C11 Undecylic has a longer carbon chain. Its smell is much more fresh and zesty.

Synthesis precursor :

Aldehyde C-11 MOA forms a Schiff base by reaction with Methyl Anthranilate or Indole for example. It can also be used for condensation with another aldehyde or ketone to form the desired alcene.

Natural availability :

Aldehyde C-11 MOA is a purely synthetic aldehyde, not found in nature.

Synthesis route :

Aldehyde C-11 MOA (for Methyl Octyl Acetaldehyde) is synthesized in two different ways. 2-Decanone reacts with a Chloroacetate to give a glycidate, which can be saponified and decarboxylated to obtain the final product. The second synthesis route firstly reacts Aldehyde C-10 Decylenic with formaldehyde in the catalytic presence of an amine, and then a hydrogenation of the intermediate product allows to obtain the Aldehyde C-11 MOA.
