The development of an efficient method for the synthesis of polysubstituted isoindolinones from 1,3-dicarbonyl Ugi-4CR adducts, employing an aromatic radical cyclization process promoted by tetrabutylammonium persulfate and 2,2,6,6-tetramethyl-1-piperidine 1-oxyl (TEMPO), is described. The protocol allowed the construction of a library of isoindolinones bearing a congested carbon in good to excellent
开发一种由1,3-二羰基Ugi-4CR加合物合成多取代异吲哚啉酮的有效方法,该方法采用了过硫酸四丁铵和2,2,6,6-四甲基-1-哌啶1-氧基所促进的芳族自由基环化工艺说明(TEMPO)。该方案允许在温和的条件下和较短的反应时间内以良好的收率构建具有拥挤碳的异吲哚啉酮文库。
