Verwenden
p-Vinylguaiacol is an aromatic substance and one of the compounds responsible for the natural aroma of buckwheat. It is also one of the major pyrolytic products of (E)-N-[(4-hydroxy-3-methoxy)-phenethyl]-3-[(3-methoxy-4-O-β-D-glucopyranosyloxy) phenyl] acrylamide; a new gycloside in tobacco.
synthetische
From vanillin by reacting with acetic anhydride and sodium acetate yielding 3-methoxy-4-hydroxycinnamic acid on sub sequent hydrolysis; the latter, heated with quinoline in the presence of hydroquinone, is decarboxylated to 4-vinylguaiacol.
Definition
ChEBI: A member of the class of phenols that is guaiacol in which the hydrogen para- to the hydroxy group is replaced by a vinyl group.
