Herein, we report a concise approach of 6,6-disubstituted 6H-benzo[c]chromenes in a two-step sequence starting from ortho-bromo benzylic alcohols and arylboronic acids, using intermolecular palladium-catalyzed C−C and intramolecular N-Iodosuccinimide (NIS) mediated key C−O bonds construction.
在此,我们报告了一种从邻溴苯甲醇和芳基硼酸开始的两步序列中 6,6-二取代 6 H-苯并[ c ]色烯的简明方法,使用分子间钯催化的 C - C 和分子内N-碘代琥珀酰亚胺 (NIS) 介导了关键的 C-O 键构建。
