The present invention relates to a process for the preparation of β-amino acids and derivatives thereof, which is especially suited for gliptins and particularly sitagliptin. A key step makes use of suitably derivatized epoxides or aziridines, which owing to a chirality provides a source of chirality for intermediates which are suitable for building up β-amino acids and similar compounds, in particular in the construction of the sitagliptin molecule.
