Rhodium-Catalyzed Formal Four-Component Reaction with Hypervalent Iodine Diazoesters, Alcohols, and Isatins for the Synthesis of Multi-functionalized Oxindoles

A novel Rh( ii )-catalyzed formal four-component reaction involving hypervalent iodine diazoesters, alcohols, and isatins was effectively established as an efficient process to produce multi-functionalized oxindoles in good to high yields.
