General description

2′-Bromoacetophenone (2-Bromoacetophenone) undergoes enantioselective addition reaction with phenylacetylene catalyzed by chiral camphorsulfonamide. It reacts with aliphatic primary amines in the presence of palladium catalyst to afford 3-methyleneisoindolin-1-ones.

Application

2′-Bromoacetophenone (2-Bromoacetophenone) was used in the synthesis of novel series of non-condensed 5,5-bicycles.
