Sustainable approaches for the synthesis of 2-substituted benzothiazoles are sought after for their use in organic chemistry, bioorganic chemistry, and industrial applications. Here, we described a visible light-driven photoredox catalytic cyclization of thioanilides to afford 2-substituted benzothiazoles using riboflavin as a photocatalyst, where oxygen is used as a clean oxidant and ethanol as a
2-取代苯并噻唑的可持续合成方法因其在有机化学、生物有机化学和工业应用中的应用而受到追捧。在这里,我们描述了使用核黄素作为光催化剂的可见光驱动的硫代苯胺的光氧化还原催化环化,以提供2-取代的苯并噻唑,其中氧气用作清洁的氧化剂,乙醇作为更环保的溶剂。这些结果为环境友好的合成提供了新的光化学路线。
