Synthesis route :
Aldehyde C-12 MNA (for Methyl Nonyl Acetaldehyde) is synthesized in two different ways.
2-Undecanone reacts with a Chloroacetate to give a glycidate, which can be saponified and decarboxylated to obtain the final product. The second route of synthesis firstly reacts Aldehyde C-11 Undecylenic with formaldehyde in the catalytic presence of an amine, and then a hydrogenation of the intermediate product allows to obtain the Aldehyde C-12 MNA.
Synthesis precursor :
Aldehyde C-12 MNA 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.
Isomerism :
Aldehyde C-12 MNA is less zesty than Aldehyde C-12 Lauric.
