  Structural characterization of folded pentapeptides containing centrally positioned β(R)Val, γ(R)Val and γ(S)Val residues

  摘要：

  A cylindrical pore of similar to 7.5 angstrom diameter containing a one-dimensional water wire, within the confines of a hydrophobic channel lined with the valine side chain, has been observed in crystals of the peptide Boc-D-Pro-Aib-Val-Aib-Val-OMe (1) (Raghavender et al., 2009, 2010). The synthesis and structural characterization in crystals of three backbone homologated analogues Boc-D-Pro-Aib-beta(3)(R) Val-Aib-Val-OMe (2), Boc-D-Pro-Aib-gamma(4)(R)Val-Aib-Val-OMe (3), Boc-D-Pro-Aib-gamma(4)(S)Val-Aib-Val-OMe (4) are described. Crystal structures of peptides 2, 3 and 4 reveal close-packed arrangements in which no pore was formed. In peptides 2 and 3 the N-terminus D-Pro-Aib segment adopted conformations closely related to Type II' beta-turns, while residues 2-4 form one turn of an alpha beta right-handed C-11 helix in 2 and an alpha gamma C-12 helix in 3. In peptide 4, a continuous left-handed helical structure was observed with the D-Pro-Aib segment forming a Type III' beta-turn, followed by one turn of a left-handed alpha gamma C-12 helix.

• SmI₂-Promoted Radical Addition of Nitrones to α,β-Unsaturated Amides and Esters:  Synthesis of γ-Amino Acids via a Nitrogen Equivalent to the Ketyl Radical
  作者：Ditte Riber、Troels Skrydstrup

  DOI：10.1021/ol027386y

  日期：2003.1.1

  [reaction: see text] Alkyl nitrones undergo radical addition reactions to a series of alpha,beta-unsaturated amides and esters when subjected to samarium diiodide via a nitrogen equivalent to a ketyl radical anion. This reaction conveniently provides access to a variety of functionalized gamma-amino acids. The methodology was extended to the asymmetric synthesis of 4-substituted gamma-amino acids,

  [反应：见正文]当烷基氮酮经相当于酮基自由基阴离子的氮与二碘化sa反应时，烷基硝酮会与一系列α，β-不饱和酰胺和酯发生自由基加成反应。该反应方便地提供了获得各种官能化的γ-氨基酸的途径。通过将硝酮自由基加成反应与具有手性助剂的丙烯酸酯/酰胺的反应，该方法扩展到了4-取代的γ-氨基酸的不对称合成。
