Copper and palladium-catalyzed sequential reactions: one-pot synthesis of isoindolo[2,1-b]isoquinolin-7(5H)-ones

Org Biomol Chem. 2019 Apr 24;17(17):4281-4290. doi: 10.1039/c9ob00440h.

Abstract

A highly efficient protocol has been developed for the synthesis of diversely substituted isoindolo[2,1-b]isoquinolin-7(5H)-ones through sequential Cu(ii)-catalyzed Sonogashira coupling, intramolecular hydroamidation followed by palladium-catalyzed ligand-free Heck reaction. Good to excellent yields (41-94%) were observed with excellent substrate scope and functional group tolerance. The developed method represents a practical strategy for the construction of bioactive isoindolo[2,1-b]isoquinolin-7(5H)-ones.
