Herein we report a bis-boric acid-mediated regioselective reductive aminolysis of 3,4-epoxy alcohols, providing new access to prepare amino diols in high diastereofidelity directly starting from nitroarenes. Notably, this step-economical process is enabled by the essential dual function of bis-boric acid, which is engaged initially in the 4,4′-bipyridine-catalyzed reduction of nitro compounds as the
在此,我们报告了双硼酸介导的 3,4-环氧醇的区域选择性还原氨解,为直接从硝基芳烃制备高非对映保真度的氨基二醇提供了新途径。值得注意的是,这一步骤经济的过程是由双硼酸的基本双重功能实现的,双硼酸最初作为还原剂参与硝基化合物的 4,4'-联吡啶催化还原,随后促进 3 的开环反应,4-环氧醇与原位生成的苯胺。
