Isoindolines are synthesized by palladium-catalyzed coupling reaction of N-(2-iodobenzyl) anilines with α,β-unsaturated N-tosylhydrazones. The reaction has several potential advantages: (1) toleration of a wide range of functional groups, (2) easy to handle and with mild conditions, (3) enriches the isoindoline family, (4) two new bonds form in one step.
吲哚啉是通过钯催化的N-(2-碘苄基)苯胺与α,β-不饱和N-对甲苯磺酰腙的偶联反应合成的。该反应具有几个潜在优势:(1) 对多种官能团具有耐受性,(2) 操作简便且条件温和,(3) 丰富了吲哚啉类化合物,(4) 一步形成两个新键。
