Organic compounds vanillin

Molecular Formula: C8H8O3


Methods of synthesis

Methods of Synthesis

  • 1874: Eugenol

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
