The ruthenium-catalyzed transfer hydrogenation of electron-rich amino-substituted acetophenones is reported. Variation of the reductant, ligands, base, and solvent allowed reaction optimization. A key discovery was the use of 1,4-butanediol as an irreversible reducing agent, which significantly improved the conversion. A range of amino- and amido-substituted aryl ketones were explored, and they all
报道了富含电子的氨基取代苯乙酮的钌催化转移氢化。还原剂、配体、碱和溶剂的变化允许反应优化。一个关键发现是使用 1,4-丁二醇作为不可逆还原剂,这显着提高了转化率。探索了一系列氨基和酰胺基取代的芳基酮,它们都以良好的收率得到了相应的醇,这表明该方法具有更广泛的适用性。
