    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。

  • 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.
  • Asymmetric synthesis of CF<sub>3</sub>-containing tetrahydroquinoline via a thiourea-catalyzed cascade reaction

    An organocatalytic asymmetric method for the synthesis of 2-CF3 tetrahydroquinoline has been achieved. The cascade reaction of 2-aminochalcones with β-CF3 nitroalkenes afforded the products bearing three contiguous stereogenic centers in good yields with excellent diastereoselectivities and enantioselectivities.
