The synthesis of twelve tetrahydro‐β‐carboline derivatives 3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h, 3i, 3j, 3k, 3l prepared via the Pictet–Spengler reaction is described. The reaction of tryptamine and a variety of arylaldehydes were carried out under ultrasonic irradiation and trifluoracetic acid catalysis at room temperature. These tetrahydro‐β‐carbolines have been synthesized in higher yields and shorter
