We develop a visible light-promoted divergent cycloaddition of α-diazo esters with hexahydro-1,3,5-triazines, leading to a series of aziridine and imidazolidine frameworks in average good yield, by simply changing the reaction media used. It is noteworthy that the reaction occurs under sole visible light irradiation without the need for exogenous photoredox catalysts. More significantly, a reasonable
我们开发了一种可见光促进的 α-重氮酯与六氢-1,3,5-三嗪的发散环加成反应,通过简单地改变所使用的反应介质,以平均良好的产率产生一系列氮丙啶和咪唑烷骨架。值得注意的是,该反应仅在可见光照射下发生,无需外源光氧化还原催化剂。更重要的是,在控制实验和密度泛函理论计算结果的基础上,提出了合理的反应机理。
