Article abstract of DOI:10.1016/S0040-4039(01)93510-5

Rearrangement of β-hydroxysulphides proceeds through an episulphonium ion which can be captured intramolecularly by the nitrogen atom of carbamates, ureas, or sulphonamides to give single diastereoisomers of pyrrolidines.With a free amine no capture takes
