- Аннотация: We developed a conceptually novel method of β-peptides synthesis based on 1,3-cycloaddition of azomethine ylides (Figure 1).[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] Figure 1. Synthesis of alternating β-proline oligomers by cycloadditive oligomerization. Reaction conditions: (i) acryloyl chloride, Et3N, CH2Cl2, 0 ˚С; (ii) R1PhCH=NCH2COR (1.0 eq), AgOAc (1.5 eq), Et3N (1.5 eq), toluene, rt. X ˗ OtBu or chiral auxiliary.
