Synthesis route :
Salicylaldehyde is synthesized by a Reimer-Tiemann reaction, reacting phenol with potash and chloroform. Then, the aldehyde function implants in the ortho position with respect to the alcohol function.
Synthesis precursor :
Salicylaldehyde is the main precursor to Coumarin synthesis by a Perkin reaction with acetic anhydride. It can also form a Schiff base by reaction with Methyl Anthranilate or Indole for example.
Isomerism :
The ortho and meta positional isomers of Salicylaldehyde are little used in perfumery, although they also have a bitter almond, very hot, balsamic and sweet smell.
