nitroarenes. The approach is based on a photochemical dearomative ring expansion starting with the conversion of the nitro group into a singlet nitrene. This process is mediated by blue light, occurs at room temperature and overall enables the insertion of the nitro N-atom into the benzenoid framework. This step transforms the aromatic starting material into a seven-membered ring azepine that, following hydrogenation
本文概述了一种从简单硝基
芳烃制备七元环内酰胺的新策略。该方法基于光
化学脱芳环膨胀,从硝基转化为单线态氮烯开始。该过程由蓝光介导,在室温下发生,总体上能够将硝基N原子插入苯环骨架中。该步骤将芳香族原料转化为七元环氮杂,然后氢化和
水解,只需三个步骤即可转化为所需的己内酰胺。
