Here, we explore a dehydrogenative 6π photocyclization method for N-substituted naphthalene carboxamides, which can be conducted in air. This method employs DMSO as both the reaction solvent and oxidant while also stabilizing the excited state of the substrate. Furthermore, the addition of photosensitizer enables the reaction to proceed under a 440–445 nm LED source via energy transfer. The proposed
在这里,我们探索了一种N-取代萘甲酰胺的脱氢6π光环化方法,该方法可以在空气中进行。该方法采用DMSO作为反应溶剂和氧化剂,同时稳定底物的激发态。此外,光敏剂的添加使反应能够在 440-445 nm LED 光源下通过能量转移进行。所提出的机制最初通过 DFT 计算得到验证。
