The title compounds 4 have been prepared from suitable β-amino-alcohol 2 and phthalic anhydride (5) in a three-step sequence in moderate to good yields (58-94%). The key step of this methodology is based on an intramolecular O-cationic cyclization involving N-acyliminium species. The high levels of the observed chemoselectivity during the intermolecular or intramolecular cyclization were also discussed.

(R)-(-)- and (S)-(+)-2-Aminobutane (1) can be synthesized in good yield and high optical purity from (S)-(+)- and (R)-(-)-2-aminobutanol (2) respectively.
