Abstract

We present an effective, visible light-driven method for the synthesis of N-(β-amino)pyrazolidin-3-ones from N-aryl glycine and azomethine imines. This additive-free protocol utilizes blue light (λ_max = 435–445 nm) at room temperature, enabling a radical-mediated cascade reaction that delivers a diverse range of pyrazolidinones in yields up to 99%. The mild conditions, high efficiency, and broad substrate scope of this process make it an attractive strategy for streamlined synthesis in drug discovery and material science.

可见光催化n -芳基甘氨酸和亚甲基亚胺级联合成吡唑烷酮的研究

我们提出了一种有效的可见光驱动方法，以N-芳基甘氨酸和亚甲基亚胺为原料合成N-（β-氨基）吡唑烷-3-酮。该无添加剂方案在室温下利用蓝光（λmax = 435-445 nm），实现自由基介导的级联反应，以高达99%的收率提供多种吡唑烷酮。该工艺条件温和，效率高，底物范围广，使其成为药物发现和材料科学中具有吸引力的流线型合成策略。
