## Abstract The first total synthesis of the β‐carboline alkaloids arenarine A **(1)** and arenarine B **(2)** is described. Methanolysis of the α‐bromoketone **9** gives **1** in good yield. Alternatively **1** can be obtained from the diazoketone **11** with boron trifluoride/methanol in poor yie
