A convenient method for the practical synthesis of resveratrol, piceatannol and pinosylvin is described. Resveratrol, pinosylvin and piceatannol can be achieved through a simultaneous demethylation and isomerization process from stilbenes with the aid of aluminum and iodine. The overall yields of the reaction were 68%, 78% and 56% (based on aromatic aldehyde). The solvent of the reaction can be reused after filtered. At the same time, quantum chemical calculations and control experiments show that iodine radical may be the key factor leading to cis-trans isomerization of double bond in the process of demethylation.

Key words: resveratrol, stilbene, demethylation, Wittig reaction, cis-trans isomerisation
