  catalysts for Henry condensation. Here, the catalytic activity of Mets7‐Cu(I) complex in Michael addition reactions has been evaluated. Furthermore, His7 peptide, in which Met residues have been substituted with His ones, was also prepared. This substitution allowed His7 to coordinate Cu (II), with the obtainment of a stable turn conformation as evicted by CD experiments. His7‐Cu (II) proved also to be

  Mets7是存在于 hCtr-1 转运蛋白中的富含甲硫氨酸的基序，参与铜细胞运输。它结合 Cu(I) 的能力最近被用来开发用于亨利缩合的金属肽催化剂。在这里，已经评估了Mets7-Cu(I) 配合物在迈克尔加成反应中的催化活性。此外，还制备了其中Met残基已被His残基取代的His7肽。这种取代允许His7与 Cu (II) 配位，获得了稳定的转角构象，如 CD 实验所驱逐。在加成反应中，His7-Cu (II)也被证明是比Mets7-Cu(I)更好的催化剂。特别是，当底物是 (E )-1-苯基-3-(吡啶-2-基)prop-2-en-1-one，观察到71%的转化率和58%的ee转化率。

  Cyclic cysteine analogues were efficiently used as constrained unnatural amino acids proving able to induce stable conformation in Leu-Val containing peptides. These ultra-short peptides were then used as chiral ligands in copper(II) complexes and applied to the asymmetric Michael addition on differently substituted chalcones.

  环状半胱氨酸类似物被有效地用作受限非天然氨基酸，证明能够在含有 Leu-Val 的肽中诱导稳定构象。然后将这些超短肽用作铜 (II) 配合物中的手性配体，并应用于不同取代的查耳酮的不对称迈克尔加成。

  Enantiomerically pure carbamate-monoprotected trans-cyclohexane-1,2-diamines are used as chiral organocatalysts for the addition of aryl ketones and acetone to nitroalkenes to give enantioenriched beta-substituted gamma-nitroketones. The reaction was performed in the presence of 3,4-dimethoxybenzoic acid as an additive, in chloroform as the solvent at room temperature, achieving enantioselectivities up to 96%. Theoretical calculations are used to justify the observed sense of the stereoinduction. (C) 2015 Elsevier Ltd. All rights reserved.
