Rh(III) catalysts have played increasingly important roles in the activation of C–H bonds to build heterocyclic scaffolds. However, there are few reports on the more challenging synthesis of pharmaceutically important 2H-isoindoles and fused 2H-isoindoles. The process reported herein is an effective strategy to produce 2H-isoindole or fused 2H-isoindole derivatives via a Rh(III)-catalyzed transformation

Conversion of α-cyanoimines 1 into α-diketimines 2 has been achieved successfully by using samarium diiodide in dry tetrahydrofuran in high yields without formation of anilinoanil 3, 1,2-diamines 4 or anilides 5.
