Several α,β,α- or α,?,α-tripeptides, consisting of a central cyclobutane β- or ?-amino acid being flanked by two d- or l-proline residues, have been synthesized and tested as organocatalysts in asymmetric aldol additions. High yields and enantioselectivit

The efficient synthesis of methyl 2-benzyloxycarbonylamino-(1S,2R)-cyclobutane-1-carboxylate starting from 2-methoxycarbonyl-(1R,2S)-cyclobutane-1-carboxylic acid is described. This β-amino acid derivative is antipodal with respect to the (1R,2S)-compound
