Synergistic catalysis: Three indole alkaloids (−)‐corynantheidine, (+)‐corynantheine and (+)‐dihydro‐corynantheine were prepared following a short and common strategy based on the binol phosphoric acid catalyzed enantioselective Pictet–Spengler reaction, followed by closure of the final ring by an intramolecular Tsuji–Trost‐type Pd‐catalyzed allylic alkylation by using an α‐ketoester‐derived enolate
