Thietane is a heterocyclic compound containing a saturated four-membered ring with three carbon atoms and one sulfur atom. [1] [2] Some derivatives are of interest as drugs. [3]

Contents

Thietane, and its derivative 2-propylthietane, are strong-smelling mouse alarm pheromones and predator scent analogues. [4] [5] Both the mouse and human olfactory receptors MOR244-3 and OR2T11, respectively, were found to respond to thietane in the presence of copper. [6]

Synthesis

Thietanes are the subject of many preparative studies. [7] [8] They are traditionally produced in modest or poor yields from 1,3-difunctionalized alkanes. [9] One example is the reaction of trimethylene carbonate and potassium thiocyanate. [10]

C4H6O3 + KSCN → C3H6S + KOCN + CO2

An improved synthesis method is the reaction of 1,3-dibromopropane and sodium sulfide. [11]

Br−(CH2)3−Br + Na2S → C3H6S + 2 NaBr

Reactions

Nucleophiles like butyllithium can open the ring in thietane. [12] Thietane also reacts with bromine. [13]
