    The Influence of Fluoroalkyl-Group Electronegativity on Stereocontrol in the Synthesis of Ψ[CH(RF)NH]Gly Peptides
    摘要:
    新型肽类仿生物分子已合成,这些分子具有不同氟化程度的CH(RF)NH单元,作为肽键的替代物。合成的关键步骤是选择性地将手性α-氨基酸酯与β-氟烷基-α-硝基乙烯进行氮的迈克尔加成。该过程的反式选择性受到氟化基团RF在β位的电负性影响,而非空间位阻的影响。当将RF的单个氟原子替换为氢或甲基时,立体控制能力急剧下降,而Br、Cl和CF3虽然比F体积更大,但在立体控制方面的结果更差。

  • The Influence of Fluoroalkyl-Group Electronegativity on Stereocontrol in the Synthesis of <i>Ψ</i>[CH(R<sub>F</sub>)NH]Gly Peptides
    作者:Alessandro Volonterio、Matteo Zanda、Serena Bigotti
    DOI:10.1055/s-2008-1072653
    日期:——
    New peptidomimetics featuring CH(RF)NH units, having different degree of fluorination, as peptide-bond surrogates have been synthesized. The key step in the synthesis consists of a stereoselective aza-Michael addition of chiral α-amino acid esters to β-fluoroalkyl-α-nitroethenes. The diastereoselection of the process was influenced by the electronegativity, rather than by the steric bulk, of the fluorinated residue RF in β-position of the nitroalkene acceptors. Replacement of a single F atom of RF by a hydrogen or methyl group brings about a dramatic drop of stereocontrol, whereas Br, Cl, and CF3, albeit bulkier than F, provide poorer results in terms of stereocontrol.

    Cinchona alkaloid catalysts were used in the Michael addition reaction of 1,3-dicarbonyl compounds to β-fluoroalkyl-α-nitroalkenes for the first time. The catalytic system performed well over a broad scope of substrates including β-keto esters and 1,3-diketones with high diastereoselectivities and excellent enantioselectivities (up to 99% ee) under mild conditions. A wide range of useful fluorinated

    asymmetric cycloaddition reaction of fluoromethyl-substituted nitroalkenes with azomethine ylides was developed using a catalyst derived from copper(I) perchlorate and a commercially available, chiral Walphos ligand. This method provides a simple approach to optically active exo-3-(fluoromethyl)proline derivatives in high yields, as well as in high diastereo- and enantioselectivities. 1,3-dipolar cycloaddition

  • Synthesis of Ψ[CH(RF)NH]Gly-peptides: The dramatic effect of a single fluorine atom on the diastereocontrol of the key aza-Michael reaction
    作者:Serena Bigotti、Stefano V. Meille、Alessandro Volonterio、Matteo Zanda
    DOI:10.1016/j.jfluchem.2008.06.018
    日期:2008.9
    We describe in full-detail the synthesis of new Psi[CH(R-F)NH]-peptidomimetics, having different fluoroalkyl groups RF, as peptide bond surrogates. A key step in the synthesis is a stereoselective aza-Michael addition of chiral alpha-amino acid esters to beta-fluoroalkyl-alpha-nitroethenes. The diastereoselection of the process was influenced by the electronegativity, rather than by the steric bulk, of the fluorinated residue R-F in the beta-position of the nitroalkene acceptors. Replacement of a single F atom of R-F by a hydrogen or methyl group brings about a dramatic drop of stereocontrol, whereas Br, Cl and CF3, albeit bulkier than F, provide inferior results in terms of stereocontrol. A mechanistic hypothesis is provided. (c) 2008 Elsevier B.V. All rights reserved.
