especially for the intermolecular tandem CDC cyclization, which represents an important strategy for constructing cyclic compounds. Herein, a three‐component tandem CDC cyclization by a Pummerer‐type rearrangement to afford biologically relevant isoindolinones from aromatic acids, amides, and DMSO, is described. This intermolecular tandem reaction undergoes a C(sp2)−H/C(sp3)−H cross‐dehydrogenative
很少报道无催化剂的多组分CDC反应,特别是对于分子间串联CDC环化而言,这是构建环状化合物的重要策略。本文描述了通过Pummerer型重排进行三组分串联CDC环化反应,以从芳香族酸,酰胺和

异吲哚啉酮。此分子间串联反应经历C(sp 2)-H / C(sp 3)-H交叉脱氢偶联,CN键形成和分子内酰胺化。该新颖方案的显着特征是避免使用催化剂和添加剂(除氧化剂外)。
