Synthesis route :
Aldehyde C-9 is an aliphatic aldehyde. Like the other aldehydes, it can be synthesized by reaction of nonyl 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 nonylic acid, using an acid chloride.
Synthesis precursor :
Aldehyde C-9 can be converted to a Schiff base in the presence of Methyl Anthranilate or Indole. It can also be used for condensation with another aldehyde or ketone to form the desired alcene.
