The synthesis of enantiomerically pure 2-aminocyclobutanecarboxylic acids has been refined to improve both the efficiency and the simplicity. These improvements provide a shorter and easier access to the racemic cis-cyclobutane β-amino acid core. Derivatization of this material with a chiral non-racemic oxazolidin-2-one allows easy diastereoisomeric separation and presents the advantage of allowing the non-destructive cleavage of the chiral auxiliary either by hydrolysis or by ammonolysis, thus providing an efficacious access to N-protected derivatives of all four stereoisomers of Boc-2-aminocyclobutanecarboxylic acid.
