η6-Arene–tricarbonylchromium complexes in the syntheses of trans-resveratrol and pinostilbene
Mendeleev Communications Pub Date: DOI: 10.1070/MC2002v012n05ABEH001616
Abstract
New syntheses of trans-resveratrol (trans-3,5,4'-trihydroxystilbene) and pinostilbene (trans-3,4'-dihydroxy-5-methoxystilbene) via nucleophilic demethylation of trimethoxystilbene were performed, whereby trans-3,5,4'-trimethoxystilbene was obtained through facilitated benzylic deprotonation of an η6-benzene-Cr(CO)3 derivative and subsequent coupling with para-anisaldehyde in an aldol-type or Wittig–Horner reaction.
