A facile one-pot synthesis of functionalized (E)-beta-arylvinyl bromides bearing various 4-alkoxycarbonyl and 4-aryloxycarbonyl groups was achieved by debrominative decarboxylation of anti-2,3-dibromo-3-(4-carboxyphenyl)propanoic acid in the presence of AgOAc and subsequent esterification in the presence of dicyclohexyl carbodiimide and dimethylaminopyridine. This method gives (E)-beta-arylvinyl bromides in high stereoselectivities and high yields, and tolerates aldehyde, ester, and nitro functional groups.
