Synthesis route :
Like the other aliphatic aldehydes, Aldehyde C-11 undecylenic, can be synthesized by a reaction of undecylenyl halides (chloride, for example) with dimethyl sulfoxide (DMSO), followed by an alkaline treatment with sodium bicarbonate. Other synthetic routes exist, such as a reduction of Rosenmund from undecylenic acid, using an acid chloride.
Synthesis precursor :
Aldehyde C-11 undecylenic 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 :
Ethyl Linalool is a constitutional isomer of Aldehyde C-11 Undecylenic. Its smell is however much more floral-fresh and less zesty.
