the catalytic pocket through simple synthetic modifications of the DNA sequence. Here, we report highly selective copper(II)-catalysed asymmetric Friedel–Crafts conjugate addition/enantioselective protonation, which is due to a careful positioning of a bipyridine ligand within a DNA framework. Most importantly, this study unveils specific structural features that account for an optimal chirality transfer

金属辅因子共价锚定至基于DNA的结构仅仅是确保将催化位点准确定位在DNA双螺旋所提供的手性微环境中的唯一方法。最终,它还允许通过简单的DNA序列合成修饰来微调催化口袋。在这里,我们报道了高度选择性的
铜(II)催化的不对称Friedel-Crafts共轭加成/对映选择性质子化,这是由于联
吡啶配体在DNA框架内的仔细定位所致。最重要的是,这项研究揭示了特定的结构特征,这些特征说明了从双链体向Friedel-Crafts加合物的最佳手性转移。
