A simple and efficient trifluoromethanesulfonic acid‐catalyzed cycloisomerization of arylpropagylsulfonamide‐tethered 2,3‐epoxycyclohexan‐1‐ols is described. The cyclization proceeds via tandem semi‐pinacol rearrangement/alkyne‐aldehyde metathesis to afford spiropiperidines under mild reaction conditions.
