A new chiral probe molecule for mono‐alcohols is developed by using 1,2‐dihydro‐1‐hydroxy‐2,3,1‐benzodiazaborine (DAB) bearing an acridine moiety 1. In the presence of mono‐alcohols, DAB 1 forms borate 2 by boronic ester formation, followed by coordination of the acridine moiety to the boron atom. Borate 2 has a chiral center on the boron atom and works as a stereodynamic circular dichroism (CD) probe
通过使用带有bearing啶基1的1,2-二氢-1-羟基-2,3,1-苯并二氮杂硼烷(DAB),开发了一种新的一元醇手性探针分子。在一元醇的存在下,DAB 1形式硼酸2由硼酸酯形成,随后吖部分与硼原子配位。硼酸盐2在硼原子上有一个手性中心,并基于the啶基团与一元醇上碳-碳不饱和基团之间的π-π相互作用,用作手性一元醇的立体动力学圆二色性(CD)探针分子。
