A highly efficient cascade aza‐MIRC (Michael Induced Ring Closure) reaction between trifluoromethylpyrazole (TFPZ)‐derived oxadienes and a ‐bromohydroxamates has been developed for the construction of 1,4‐oxazepinone derivatives. The reaction proceeds smoothly under mild conditions via a cascade Aza‐Michael addition/intramolecular S N 2 sequence, and features broad substrate scope, transition‐metal free, operational simplicity etc. The utility of the versatile protocol was also demonstrated by gram‐scale reaction and valuable synthetic transformations.
