We report a DFT study of a Bergman cyclization producing a stable triplet nitroxide diradical and monoradical (after H abstraction from an external source). The monoradical is predicted to be amenable to detection by EPR methods to potentially probe the structure and dynamics of enediyne molecules for drug interactions.
我们报告了一项密度泛函理论(DFT)研究,该研究涉及 Bergman 环化反应,生成了一种稳定的三重态氮氧自由基二聚体和单自由基(在从外部源进行 H 原子提取后)。预测单自由基可以通过电子顺磁共振(EPR)方法进行检测,从而有可能探测烯二炔分子的结构和动力学,以研究药物相互作用。
