'Ole in one! Treatment of β‐amino alcohols with CS2 under alkaline conditions gave 1,3‐thiazolidine‐2‐thiones, which were then treated with benzyne generated in situ. The reaction underwent an unprecedented addition–elimination process to give the desired olefins in 60–87 % yields (see scheme; DBU=1,8‐diazabicyclo[5.4.0]undec‐7‐ene).
