The synthesis of tetrahydroisoquinolines and tetrahydro-b-carbolines, using the Pictet-Spengler reaction, was carried out in the presence of a catalytic amount of o-benzenedisulfonimide, which worked as a Brønsted acid organocatalyst. The reaction conditions were mild and green and good target produ
