Succinct and stereoselective: A high‐yielding two‐step indole ring installation comprising the Stille cross‐coupling and a PdII‐mediated oxidative heterocyclization was exploited in a concise total synthesis of paspalinine. The trans‐anti‐trans CDE fused ring system of the heptacyclic natural product was established highly stereoselectively through hydroxy‐directed cyclopropanation and allylic selenoxide
