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。
