Synthesis route :
Aldehyde C-8 is an aliphatic aldehyde. Like the other aldehydes, it can be synthesized by reaction of octyl halides (chloride, for example) and dimethyl sulfoxide (DMSO), followed by an alkaline treatment with sodium bicarbonate. Other synthetic routes exist such as a reduction of Rosenmund from octylic acid, using an acid chloride.
Synthesis precursor :
Aldehyde C-8 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 :
1,3 Octenol and Methyl Hexyl Ketone are constitutional isomers of Aldehyde C-8. However, their smell is very different, as they are more earthy and reminiscent of mushroom.
