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]

\mathrm {C_{4}H_{6}O_{3}+\ KSCN\longrightarrow \ C_{3}H_{6}S+\ KOCN+\ CO_{2}}

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

\mathrm {Br-(CH_{2})_{3}-Br+\ Na_{2}S\longrightarrow \ C_{3}H_{6}S+2\ NaBr}

Reactions

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