Guaiacol is also present in wood smoke, as a product of pyrolysis of lignin. As shown in Scheme 1, guaiacol (2-methoxyphenol) is treated with sodium ethoxide to give a sodium salt which is quenched with an epoxyalkene. The final step involves the oxidation of the alkene to the diol using potassium permanganate [4 ]. Sign in to download full-size image Scheme 1.
