Synthesis of resveratrol by Ashleybeth Martinez and Lanny Lantigua



Phelicia Slade

The reaction of 3,5-dihydroxybenzaldehyde (I) with Tbdms-Cl gives the disilylated aldehyde (II), which by a Wittig condensation with methylenetriphenylphosphorane (III) yields the 3,5-dihydroxystyrene (IV). The reaction of (IV) with acetic anhydride and pyridine affords 3,5-diacetoxystyrene (V), which was submitted to a Heck condensation with 4-acetoxyiodobenzene (VI) by means of Pd(OAc)2 and PPh3 in hot acetonitrile to provide 3,4',5-triacetopxy-(E)-stilbene (VII). Finally, this compound is deacetylated by means of NaOMe in THF/methanol to furnish the target resveratrol. Thank You!!!!
