Stereochemically pure methylsulfinates 3 and benzylsulfinamides 4 are readily epimerized in the presence of hydrogen chloride and at the same time they can be transformed by sulfinate-sulfinamide interconversion.Formation of sulfinyl chlorides 2 as intermediates and their epimerization by rapid chloride anion exchange at sulfur atom is proposed.The equilibrated ratio between epimers 2a and 2b determines the enantioselectivity of these processes.
