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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
