Rhodium-Catalyzed Ring Expansion and Ring Opening of ­Azetidines: Domino Conjugate Addition/Inert-Bond Activation

Abstract

Domino conjugate addition/inert bond activation is a useful strategy to improve the efficiency of synthesis. We summarize the reports on the domino conjugate addition/inert bond activation, and its applications in the rhodium-catalyzed ring expansion and ring opening of azetidines.
