α-Dicarbonyl systems reacted with vinylmagnesium bromide and acetic anhydride to give α-acetoxy-α-vinylalkanones.These substrates react with benzylamine in the presence of tetrakis(triphenylphosphine)palladium to give N-benzylpyrroles with substituents in the two and/or three position.The functiodifferentiated synthesis of α-dicarbonyl compounds from ketones makes this a pyrrole annulation onto any α-methylene carbonyl system.
