We developed a conceptually novel method of β-peptides synthesis based on 1,3-cycloaddition of azomethine ylides [1]. Short well-defined β-proline oligomers with up to 6 monomeric pyrrolidine units were synthesized in racemic and non-racemic forms and characterized by X-ray and CD [1,2]. Some oligomeric derivatives revealed potent antiproliferative activity against hormone-refractory prostate cancer cell line PC-3 [2,3]. References [1] K. V. Kudryavtsev, P. M. Ivantcova, A. V.
