—— | 4-(formylphenyl) (E)-4-(2-bromovinyl)benzoate | 1132093-94-7 | C16H11BrO3 | 331.166 |
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.
