Highly Enantioselective Synthesis of Linear β-Amino Alcohols

β-Amino alcohols derived from α-amino acids have been extensively used as a powerful source of chirality. Transforming the alcohol moiety into a good leaving group has allowed the rearrangement of these β-amino alcohols and the introduction of a large number of nucleophiles through the anchimeric participation of the nitrogen atom. An overview on the recent progress realized on the rearrangement of these β-amino alcohols in the presence of (CF₃CO)₂O and H₂SO₄ is reported.
