摘 要:以脯氨酸为前体,设计并合成了一种新的含氟配体,并将其应用到铜催化的亨利反应中。以硝基甲烷和对硝基苯甲醛的反应为模板反应,考察了配体、铜源、溶剂和碱对反应收率的影响,对反应条件进行了优化。以含氟脯氨酸衍生物为配体,乙酸铜为铜源,甲醇作溶剂,三乙胺作为碱,不同取代基的芳香醛和硝基烷烃在室温下反应,得到53%~98%的收率。A new fluorous proline-derived ligand has been synthesized and applied to the copper-catalyzed Henry reaction. The reaction conditions were optimized in terms of ligand, Cu source, solvent and base taking the reaction of 4-nitrobenzaldehyde and nitromethane as a model reaction. The optimized conditions are:using fluorous proline imide as ligand, copper acetate as copper source, methanol as solvent and triethylamine as base and the reaction was carried out at room temperature. A wide range of substrates were investigated under the optimized conditions and the yields of the target products varied from 53% to 98%.
