  Novel α,α-disubstituted α-aminoacids with axial dissymmetry and their N- or C-protected derivatives

  摘要：

  Racemic as well as enantiomerically pure 1,1'-binaphthyl-substituted alpha-aminoisobutyric acid (Bin), a new chiral atropoisomeric alpha, alpha-disubstituted glycine, and its biphenyl analogue (Bip), have been prepared with good yields by bis-alkylation of a glycine tert-butyl ester Schiff base with 2,2'-bis(bromomethyl)-1, 1'-binaphthyl and 2,2'-bis(bromomethyl)-1,1'-biphenyl, respectively, under phase transfer conditions. The free aminoacids Bin and Bip, as well as their N-protected (Z, Boc, Fmoc) and/or C-protected (ethyl or tert-butyl esters) derivatives, useful for the incorporation of these new aminoacids into peptides, have been obtained. A slow interconversion between the two enantiomers of the Bip derivatives is generally observed in H-1 NMR at room temperature, with a rotational energy barrier of 59 kJ mol(-1).

  Practical resolution of an atropoisomeric α,α-disubstituted glycine with l-phenylalanine cyclohexylamide as chiral auxiliary

  摘要：

  L-Phenylalanine cyclohexylamide has been used as a chiral auxiliary for the medium-scale resolution of 2',1':1,2;1 ",2 ":3,4-dinaphthcyciohepta- 1,3-diene-6-amino-6-carboxylic acid (Bin), an alpha,alpha-disubstituted glycine with only axial dissymmetry. Coupling of X-Bin-OH (X=Ac; Bz) with H-(L)-Phe-NH-C6H11 by the EDC/HOBt method gave the dipeptide diastereoisomers X-(R)-Bin-(L)-Phe-NH-C6H11 and X-(S)-Bin-(L)-Phe-NH-C6H11, which were separated by crystallization (X=Bz) and/or chromatography. Extensive acidic hydrolysis, followed by esterification of the resulting free amino acid enantiomers, led to enantiomerically pure (-)-(R)-H-Bin-OMe and (+)-(S)-H-Bin-OMe with high yields.

  A variety of model peptides, including four complete homologous series, to the pentamer level, characterized by the recently proposed binaphthyl-based, axially chiral, Cα-tetrasubstituted, cyclic α-amino acid Bin, in combination with Ala, Gly, or Aib residues, was synthesized by solution methods and fully characterized. The solution conformational propensity of these peptides was determined by FT-IR

  多种模型肽，包括四个完整的同源系列，达到五聚体水平，其特征是最近提出的基于联萘的轴向手性 Cα-四取代的环状 α-氨基酸 Bin，与 Ala、Gly 或 Aib 残基组合, 通过溶液法合成并充分表征。这些肽的溶液构象倾向通过FT-IR吸收和1H-NMR技术确定。此外，通过 X 射线衍射在晶体状态下评估了游离氨基酸 (S)-对映异构体和具有异手性序列 -(R)-Bin-Phe- 的 Nα-酰化二肽烷基酰胺的分子结构。综上所述，结果表明含Bin的肽优先采用β-弯头和310个螺旋，尽管在某种程度上，短低聚物在溶液中也会采用完全延伸的构象。我们还证实了 (R)-Bin 将肽链折叠成右手弯曲和螺旋结构的趋势。Bin 残基的绝对构型与 225 nm 附近 1Bb 联萘跃迁的典型强烈激子分裂棉花效应相关。
