Carbohydrate thionolactones may be efficiently synthesized from the corresponding 1-thio sugars via a two-step procedure involving formation of a glycosyl phenylthiosulfinate by treatment with either phenylsulfinyl chloride or 1-(phenylsulfinyl)piperidine (BSP), and subsequent thermal elimination in toluene.

commercially available tert-butylsulfinyl chloride in toluene at room temperature, followed by thermolysis. The method can also be used to generate reactive thioaldehydes and thioketones directly from thiols, which can be trapped in situ with a suitable diene.
