Thietane is a heterocyclic compound containing a saturated four-membered ring with three carbon atoms and one sulfur atom.[1][2]

Thietane, and its derivative 2-propylthietane, are strong-smelling mouse alarm pheromones and predator scent analogues.[3][4] Both the mouse and human olfactory receptors MOR244-3 and OR2T11, respectively, were found to respond to thietane in the presence of copper.[5]

Synthesis

Thietane can be produced from the reaction of trimethylene carbonate and potassium thiocyanate, but the yield is low.[6]

An improved synthesis method is the reaction of 1,3-dibromopropane and sodium sulfide.[7]

Reactions

Nucleophiles like butyllithium can open the ring in thietane.[8] Thietane also reacts with bromine.[9]
