A facile and efficient method for the synthesis of N-substituted isoindolin-1-one derivatives from 2-formylbenzoic acid and amine under Pd(OAc)2/HCOOH system has been described. The whole process is carried out in ligand-free conditions and furnished the desired products by reductive intramolecular cyclization. Furthermore, this procedure is applied successfully for the modification of natural products
已经描述了在Pd(OAc)2 / HCOOH体系下由2-甲酰基苯甲酸和胺合成N-取代的异吲哚啉-1-酮衍生物的简便有效的方法。整个过程在无配体条件下进行,并通过还原分子内环化作用提供所需的产物。此外,该程序已成功应用于天然产物的改性,如长春新碱和雌酮。
