—— | (E)-4-(2-bromovinyl)benzoic acid | 959472-50-5 | C9H7BrO2 | 227.057 |
A facile one-pot synthesis of functionalized (E)-β -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)-β - arylvinyl bromides in high stereoselectivities and high yields, and tolerates aldehyde, ester, and nitro functional groups.
