  • <b>Hexafluoroacetone as a Protecting and Activating Reagent: Synthesis of New Types of Fluoro-Substituted α-Amino, α-Hydroxy and α-Mercapto Acids</b>
    作者:Klaus Burger、Sergej Osipov、Torsten Lange、Pavel Tsouker、Jan Spengler、Lothar Hennig、Beate Koksch、Stefan Berger、Salah El-Kousy
    DOI:10.1055/s-2004-829131

    (S)-malic, (S)-citramalic and (S,R)-thiomalic acid, new types of 4,4-difluoro-substituted a-ami- no-, a-hydroxy- and a-mercaptopentanoic acids have been synthe- sized, applying hexafluoroacetone as protecting and activating reagent. The new partially fluorinated a-functionalized carboxylic acids represent interesting monomers for peptide and depsipeptide modification and for rational design and elucidation
    从(S)-天冬氨酸、(S)-苹果酸、(S)-柠苹果酸和(S,R)-硫代苹果酸开始,新型4,4-二氟取代的α-氨基-、α-羟基-和α-巯基戊酸已被合成,使用六氟丙酮作为保护和活化试剂。新的部分氟化的α-官能化羧酸代表了用于肽和缩肽修饰以及合理设计和阐明二级结构的有趣单体。
  • A New Method for the Synthesis of (S)-α-Methylisoserine and Its Incorporation into Peptides
    作者:Raul Pires、Klaus Burger
    DOI:10.1055/s-1996-4387
    日期:1996.11
    (S)-(+)-Citramalic acid is converted into isocyanate 4 using hexafluoroacetone as the protecting agent. Isocyanate 4 represents a doubly activated species, which upon reaction with alcohols provides N-protected, carboxyl-activated α-methylisoserine derivatives, perfectly suited for peptide synthesis (5 → 8). Acylation of 4 with N-protected amino acids gives fully protected carboxyl-activated dipeptides. Ring opening with amino acid esters results in the formation of tripeptides (9 → 10).
    (S)-(+)-柠檬酸被转化成异氰酸酯4,使用六氟丙酮作为保护剂。异氰酸酯4是一种双重活化的物质,当其与醇反应时,产生了N-保护、羧基活化的α-甲基异丝氨酸衍生物,非常适合用于多肽合成(5 → 8)。用N-保护的氨基酸对4进行酰化作用,得到完全保护的、羧基活化的二肽。用氨基酸酯进行环开反应,形成了三肽(9 → 10)。
  • Efficient stereoconservative syntheses of 4,4-difluoro-2-hydroxybutyric acids from (S)- and (R)-malic and (S)- and (R)-citramalic acid

    A preparative simple stereoconservative synthesis of homochiral 4,4-difluoro-2-hydroxybutyric acid and 4,4-difluoro-2-hydroxy-2-methylbutyric acid using hexafluoroacetone as protecting and activating agent is described.

  • New Stereoconservative Syntheses of β,β,β- and γ,γ,γ-Trifluoro-α-amino, α-Hydroxy, and α-Mercapto Acids and Their Incorporation into a Peptide and Depsipeptide Fragment
    作者:Hartmut Schedel、Wojciech Dmowski、Klaus Burger
    DOI:10.1055/s-2000-8198
    日期:——
    Syntheses of β,β,β- and γ,γ,γ-trifluoro-α-amino, α-hydroxy and α-mercapto acids using hexafluoroacetone as protecting and activating reagent are described. The key step of the syntheses is the transformation of an ω-carboxy group into a trifluoromethyl group on treatment with sulfur tetrafluoride. The carboxy activated species obtained are suitable for direct incorporation into peptide and depsipeptide fragments. RP-HPLC experiments and Mosher's TMPA method (1H and 19F) demonstrate that the reaction sequence occurs without racemization.
    描述了使用六氟丙酮作为保护和活化试剂合成β、β、β-和γ、γ、γ-三氟-α-氨基、α-羟基和α-巯基酸。合成的关键步骤是用四氟化硫处理将β-羧基转化为三氟甲基。获得的羧基活化物质适合直接掺入肽和缩酚肽片段中。 RP-HPLC 实验和 Mosher 的 TMPA 方法(1H 和 19F)证明反应序列的发生没有外消旋作用。
  • New building blocks for peptide and depsipeptide modification N-glycosylated l-malic and l-citramalic acid derivatives
