Brevity is the soul of wit! The power of SmI2‐induced cyclizations has been demonstrated by the shortest formal totalsynthesis of (±)‐strychnine to date, which features a new cascade reaction. Only one protective‐group transformation is required. The ketyl–aryl coupling/acylation cascade also efficiently proceeds with other indole derivatives with excellent diastereoselectivities.
