通过X射线衍射对p BrBz-(Aib- L Ala)5 -OMe四水合物和p BrBz-(Aib - L Ala )6 -OMe二水合物进行了晶体结构分析。十肽和十二肽分子基本上都是α-螺旋,分别具有五个和七个1 5分子内H键。在C末端附近也可以看到两个结构之间的相似性,其中α螺旋的规则性被破坏,有利于形成1到4和1到6类型的分子内H键。进行了与球形蛋白质中存在的螺旋的参数和相互作用特征的简要比较。

The nickel(II)-catalyzed ortho-arylation of unactivated C–H bonds utilizing amino acids as directing groups with aryl iodides or bromides as coupling electrophiles is described. This protocol features excellent mono-selectivity, good regioselectivity, and wide functional group tolerance. Additionally, the obtained products bearing a biaryl motif and an amino acid represent bioactive molecules with
描述了镍 ( II ) 催化的未活化 C-H 键的邻位芳基化,利用氨基酸作为导向基团,芳基碘化物或溴化物作为偶联亲电体。该协议具有优异的单选择性、良好的区域选择性和广泛的官能团耐受性。此外,获得的带有联芳基基序和氨基酸的产物代表了具有广泛生物活性的生物活性分子。
