New bicyclic heterocycles 5, which are potentially useful for the enantioselective synthesis of substituted β-amino acids, have been synthesized. A study on the α-alkylation of these chiral auxiliaries is presented. An optically pure β-amino acid was obtained in excellent yield from its masked chiral derivative 6a.
