An efficient two-step synthesis of alkylidenecyclopropanes is reported based on the addition of metallated cyclopropyl thiol esters to carbonyl compounds. Thermolysis of the resulting α-spirocyclopropyl-β-lactones at 105-150°C induces thermal [2+2] cycloreversion to furnish alkylidenecyclopropanes in good yield.
