a metal-free, environment-friendly photoredox-catalyzed sulfonylation of phenylhydrazines using thiols, employing MeCN:H2O as a green solvent and eosin Y as a photoredox catalyst. This strategy exhibits a broad substrate scope and good functional group compatibility, including hetero(aryl) as well as aliphatic phenylhydrazines. Finally, this protocol also demonstrated good application for the synthesis
磺酰化方法是一种简单有效的合成磺酰胺的方法。尽管在构建磺酰胺框架方面取得了进展,但苯肼作为胺化源的潜在用途仍有待探索。在此,我们报道了一种无金属、环境友好的光氧化还原催化苯肼磺酰化反应,采用硫醇,采用MeCN:H 2 O作为绿色溶剂,曙红Y作为光氧化还原催化剂。该策略表现出广泛的底物范围和良好的官能团兼容性,包括杂(芳基)以及脂肪族苯肼。最后,该方案还证明了其在药物类似物合成中的良好应用。
