Synthesis route :
Like the other aliphatic aldehydes, Aldehyde C-11 undecylic, can be synthesized by reaction of undecanyl 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 undecylic 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.
It is used for a Knoevenagel condensation for the synthesis of Ozonil®.
Isomerism :
Undecavertol® is a constitutional isomer of Aldehyde C-11 undecylic. Its smell is however very different.
