Efficient Synthesis of Hydroxyl Isoindolones by a Pd‐Mediated CH Activation/Annulation Reaction

Abstract

Radical reaction: A convenient synthesis of hydroxyl isoindolones by a Pd-catalyzed CH activation/annulation reaction with near "click chemistry" efficiency is presented (see scheme; TBHP=tert-butyl hydrogen peroxide). This methodology features short reaction times (10-30 min), high atom economy, wide substrate scope (22 examples), and good reaction yields (up to 93 %).
