A total synthesis of the racemic natural product tylophorine [(±)-1] has been demonstrated using the palladium-catalyzed carboamination method developed by Wolfe and co-workers. In this case, an electron-rich aryl bromide 18 was prepared in four steps and subjected to palladium-catalyzed Wolfe carboamination conditions with olefinic carbamate 7 to provide the racemic 2-(arylmethyl)pyrrolidine (±)-19
