synthesis of not only racemic decursivine and serotobenine, but also enantiopure (+)‐ and (−)‐decursivine and a variety of their analogues. The present syntheses represent the shortest pathway for the total synthesis of decursivine and serotobenine to date. Moreover, the newly developed cascade sequence for the total synthesis of decursivine does not need any protecting steps. The scope and the reaction

A photo op: The concise total syntheses of (±)‐decursivine and (±)‐serotobenine were achieved by using the titled cascade reaction, which is modeled on the biomimetic pathway. The synthesis of (±)‐decursivine, which exhibits antimalarial activity, was carried out in five steps without using protecting groups.
