A highly stereoselective procedure for the preparation of a variety of syn 2-amino alcoholderivatives from enantiopure E-γ-hydroxy-α,β-unsaturated phenyl sulfones is described. The method is based on an intramolecular carbamate cyclization, followed by functionalization at α-position by reaction of the sulfonyl carbanion with electrophiles, and subsequent elimination of the sulfonyl group.
