Three‐step cascade: Oxazepine derivatives were efficiently prepared from O‐propargylic oximes and dipolarophiles through copper‐catalyzed cascadereactions which proceed through a 2,3‐rearrangement, [3+2] cycloaddition, and subsequent 1,3‐oxygen rearrangement. The process involves the cleavage of CO and NO bonds.
