methods of synthesis
Methods of Synthesis
  • 1874: Eugenol
  • 1920’s: Lignin
  • Now: Guaiacol
two step synthesis guaiacol
Two-Step Synthesis:Guaiacol
  • Guaiacol and glyoxylic acid react to produce vanillylmandelicacid
  • The addition of 4-Hydroxy-3-methoxyphenylglyoxylic acidresults in oxidative decarboxylation
  • Vanillin is produced
