Attempt to Synthesize 2,3,5,4′-Tetrahydroxystilbene Derived from 2,3,5,4′-Tetrahydroxystilbene-2-O-β-glucoside (THSG)
An attempt to synthesize aglycone 1 derived from 2,3,5,4'-tetrahydroxystilbene-2-O-β-glucoside (THSG) via the Wittig reaction and Mizoroki?Heck reaction is described. In the Wittig protocol, 2,3,5,4'-tetramethoxystilbene 2 was obtained. Additionally, a palladium-catalyzed Mizoroki?Heck reaction strategy yielded 2-aryl-2,3-dihydrobenzofuran 13 instead of derivative 12 in good yield.
