difunctionalization of alkynoates has been accomplished. This procedure provides a new strategy toward synthesis of the coumarin core structure by photoredox-mediated oxidation to generate the α-oxo radical, which supervenes a domino radical addition/cyclization reaction in moderate to good yields with high regioselectivity at ambient temperature.
已经实现了可见光促进的炔属酸酯的温和直接双官能化。该方法为通过光氧化还原介导的氧化合成
香豆素核心结构以产生α-氧代自由基提供了新的策略,该α-氧代自由基在环境温度下以中等至良好的产率,高产率地取代了多米诺骨牌自由基加成/环化反应。
