The regio- and stereoselective preparation of 1,3-aminoalcohol derivatives from protected allylamines via intramolecular participation by the sulfinyl group is reported. A carbamate protecting group on nitrogen leads to products arising from nucleophilic participation by both the sulfinyl and carbamate groups, while protection as the sulfonamide affords the product arising from sulfinyl group participation alone.
