A H4SiW12O40-catalyzed three-component tandem reaction of 2-acylbenzoic acids, primary amines and phosphine oxides to form 3,3-disubstituted isoindolinones was developed. By employing H4SiW12O40 as the catalyst and dimethyl carbonate (DMC) as the solvent, a diverse range of 2-acylbenzoic acid derivatives and primary amines worked well to give the C3-phosphinoyl-functionalized 3,3-disubstituted isoindolinones
开发了AH 4 SiW 12 O 40催化的2-酰基苯甲酸、伯胺和氧化膦的三组分串联反应以形成3,3-二取代异吲哚啉酮。通过使用 H 4 SiW 12 O 40作为催化剂和碳酸二甲酯 (DMC) 作为溶剂,各种 2-酰基苯甲酸衍生物和伯胺都能很好地产生 C3-膦酰基官能化的 3,3-二取代异吲哚啉酮收率范围为61%-87%。这种转化的优点包括绿色催化剂和溶剂、可用的起始原料、广泛的底物范围、高效率和操作简单,水作为唯一的副产物。该策略实现了高效、绿色的分子片段组装来获取异吲哚啉酮,这将为以绿色方式合成潜在的生物活性分子提供机会。
