NHC-Catalyzed intramolecular benzoin condensation–oxidation is developed for the expedient synthesis of diverse cyclic 1,2-diketones incorporated in dibenzo-fused seven-membered heterocycles in good to excellent yields, under ambient conditions. The presented carbene-catalyzed transformation appears to proceed through the benzoin intermediate followed by aerobic oxidation.
NHC催化的分子内安息香缩合-氧化技术是在环境条件下,以良好至极佳的收率,方便地合成掺入二苯并稠合七元杂环的各种环状1,2-二酮。提出的卡宾催化的转化似乎通过安息香中间体进行,然后进行好氧氧化。
