Starting from the chiral building block 1, which is readily available from natural aspartic acid, a concise and versatile synthesis of optically active β-amino acids including β-proline derivatives is reported. Regioselective transformations of the 1,4-bis-electrophile 2 are facilitated by an anchimeric participation.
